Description of problem: When trying to boot the F7 test 3 Live CD I get a message "Warning: Cannot find root file system. Create symlink for /dev/root" and I get a shell prompt. there is no entry for the CD drive in /dev Version-Release number of selected component (if applicable): How reproducible: every time Steps to Reproduce: 1. insert Live CD in cd drive 2. boot 3. Actual results: Message warning cannot find root file system Expected results: Live cd to boot up. Additional info: This system uses IDE hard drives and CD_RW drive. The current rawhide kernels do not see the CD drive either. This system uses the SiS chip set and pata_sis.
Can you provide the output of lspci as well as a dmesg from a running system where the CD drive isn't being found?
here is the lspci: (dmesg attachment to follow) [root@localhost ~]# lspci 00:00.0 Host bridge: Silicon Integrated Systems [SiS] 661FX/M661FX/M661MX Host (rev 11) 00:01.0 PCI bridge: Silicon Integrated Systems [SiS] SiS AGP Port (virtual PCI-to-PCI bridge) 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS963 [MuTIOL Media IO] (rev 25) 00:02.1 SMBus: Silicon Integrated Systems [SiS] SiS961/2 SMBus Controller 00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] AC'97 Sound Controller (rev a0) 00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 00:03.3 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller 00:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

My system (also with IDE hard drives, a DVD-RW drive and a SiS IDE interface) has also got this problem with the Fedora 7 test 3 Live CD. Before it gives the 'cannot find root file system' warning it generates a kernel panic after probing [pata_sis]. This error also occurs with Fedora 7 test 1 and Fedora 7 test 2. As mentioned in the "F7T4 and SATA/IDE testing - a call to arms!" posting ("https://www.redhat.com/archives/fedora-test-list/2007-April/msg00289.html") on the fedora-test mailing-list, I'll attach "dmesg.txt" and "lspci.txt" generated on my system to this bugzilla report. ps. I also tried the current (17 april 2007) Fedora Development snapshot of "boot.iso" with an FTP-install. This also gives a kernel panic after probing [pata_sis]. It does get to the partioning screen but Anaconda doesn't find any hard drives to install to.

I need the info from the kernel panic, even if you have to attach it as a jpeg from a digital camera 8)
I have the same problem with the latest development boot.iso.

Today I tried the Fedora Development "boot.iso" snapshot of 2007.04.21. This time the [pata_sis] module loaded correctly, without any kernel oops. Anaconda did also find my hard drive this time. The patch in "kernel-2.6.20-1.3094.fc7" seems to have fixed this problem. Thanks for the patch...
Great... thanks for the confirmation!
The original problem reported on this bug still exists with the rawhide-20070419.1-i386-live.iso. The dmesg and lspci output look the same with the kernel-2.6.20-1.3094.fc7 from todays rawhide. The patch may have fixed the oops but not the original problem. bug reopened.
(In reply to comment #20) Peter van Egdom reported that 20070421 is fixed, you are using 20070419, so you should probably try newer version.
With the Test 4 Live CD (F-6.93-i386-Live.iso) the failure occurs sooner in the boot sequence. After selecting "Run from image" (or any of the other options) from the initial menu, all I get is: "loading vmlinuz..................isolinux: Disk error 80, AX=4200, drive 9F Boot failed: press a key to retry..." Please let me know if there is any other information I can provide. Btw, booting an old 2.6.18 kernel shows that the hardware is working - class: CDROM bus: IDE detached: 0 device: hdd desc: "SAMSUNG CD-R/RW SW-252S" -
A day or two within FC7T4 coming out, I did a rawhide install, and I too have the SiS MB, or MSI 7060 is what it's called. Here is my lspci output in case it helps.

But I am current with rawhide (up until the merge anyway) and everyone works. Although I have seen the pata_sis module being mentioned, and I don't have any pata drives if that matters, just IDE.
Re: comment #23: > I don't have any pata drives if that matters, just IDE. PATA and IDE are two names for the same thing. Re: comment #22: > isolinux: Disk error 80, AX=4200, drive 9F That's probably a bad CD burn. Try burning the CD again, preferably on some different media. Actually, can you try using the latest LiveCD from http://torrent.fedoraproject.org/ - that should definitely have the patch needed.
Same problem here, on an old Acer TravelMate 612TX (Pentium III 900, 512 MB RAM, HDD 40 GB IDE, CD-ROM IDE, i815 chipset). When booting the LiveCD, the kernel starts but then the IDE CD recognized with 1 sector of 512 bytes (!), and (obviously) the root FS is not mounted, and after some IDE errors and retries a shell prompt appears. This happened since F7test1; up to test3 I used to have problems also on other "old" hardware (e.g. a desktop PIII probably with a VIA chipset) but now test4 boots with no problem on that hardware; however it still fails on the laptop. I had no problem so far with FC3 to FC6 on the same laptop; if this can be useful, I can boot the intalled FC6 and send you the output of lspci and/or dmesg from that version; I also can send a picture of the laptop screen; anyway the important part seems: sdb: sector size 0 reported, assuming 512 SCSI device sdb: 1 512-byte hdwr sectors (0 MB) sdb: Write Protect is off sdb: Mode Sense: 00 00 00 00 sdb: cache data unavailable (the above lines repeated another time, then:) sdb: assuming drive cache: write through sdb:<3>ata2.00: exception Emask ata2.00: cmd a0/01:00:00:.... res 40/00:03:00:.... I am available to test a modified LiveCD if this can be useful. Elio

I downloaded and booted with the 5/02 Live CD and it booted fine, although was very slow and thought there was way too many services trying to start for a live cd lookat-only. The only thing it did, was while firefox was open, I configured my network, and when it went to an online page, it froze and had to hit reset button. But the cdrom booted up with my info above.
re: comment 24 disk error; I burned another copy of the bittorrent rawhide-20070502-i386-Live.iso and it produces the original error. "warning: Cannot find root file system! create symlink dev root etc... The output on the screen as it is booting the kernel looks like the attached dmesg up to the point where it ends the retries on ata2.01. At that point it produces the error about not finding dev root.

Created attachment 155980 [details] Screenshot on Acer TM612TX I tried the Fedora 7 KDE Live CD (final version) and it still doesn't work on my laptop. You can see the screenshot; it keeps repeating the last lines. Are there any plans to fix this problem? Elio
Elio: your bug is different to the other problems in this bug entry. We do plan to fix the problem with one or two CD drives having trouble after SRST but it will take time and the work will be done upstream initially.
Thank you, Alan. If I can help testing "should-be-fixed" versions on my laptop (assuming that it survives...) please let me know. On a (totally urelated and off-topic here, but I don't know where to ask): I am requesting the inclusion of MySQL support in the standard Fedora RPM since 2006-03-15, with no success; this is the Bugzilla reference: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=185515 . Are there any other ways to ask for a simple feature addition like this one? Thanks, Elio
What are the prospects for getting this fixed? Should I file a separate bug against the kernel since I can not use my CD-RW drive at all?
Two SiS fixes have gone upstream for the next kernel. A fix has also gone upstream for some of the more recalcitrant CD devices. Whether that fixes a specific case is hard to guess in advance
(In reply to comment #35) > Two SiS fixes have gone upstream for the next kernel. A fix has also gone > upstream for some of the more recalcitrant CD devices. Whether that fixes a > specific case is hard to guess in advance Which -rc are they in? I was going to try to put up a new set of rawhide live images this week anyway and can try to make sure to coordinate with davej to ensure there's a new enough kernel for seeing if that helps Richard out.
git head at the moment. We should be pretty close to 2.6.22 final anyway
Everything relevant should be in -rc5 from a quick inspection. There is some more stuff in 2.6.22-rc4-mm but that shouldn't be related.
Great. -rc5 is in rawhide; I'll try to get a live CD fitting with it today (we were slightly over last week, *sigh*) and put it out for people to try
Created attachment 157394 [details] dmesg from booting 3228 kernel the 3228 kernel is still not seeing the CD drive
You may as well close this bug since the CD drive is at least being recognized. I'll open another bug about how it takes approx. 2:45 minutes to actually load the driver and then other similarly long times to progress through the rest of the boot process. Thanks for your work, Richard
