Description of problem:fc6 will not complete loading with kernel
2.6.20-1.2948.fc6 update. It stops during "Starting udev" with following report:
kernel BUG at include/linux/timer.h:82! invalid opcode: 0000 [#1] SMP last sysfs
file: <This varies. one was /block/hdc/removeable, another
/class/usb_endpoint/usbdev, another /block/ram5/dev>.
fc6 loads fine with the .18 kernel. I also have FC-5 loaded and a recent update
put in the 2.6.20 kernel and it loads fine. It has a different -1.XXXX number
than the one in fc6.
Version-Release number of selected component (if applicable):kernel
How reproducible:Software upgrade
Steps to Reproduce:
1.Load FC6 respin 20070401.
2.yum upgrade (It downloads 111 packages)
Actual results: Stopped loading during "Starting udev" line
Expected results: Complete loading & run fc6
Additional info:There is a large amount of data presented after the crash which
seems to include register contents and then another screen of what looks to be
memory contents. I have no idea how to save this stuff as fc6 is not yet
running. It did not show in dmesg or /var/log/messages after running fc6 with
Steps to Reproduce:
1. Install FC6 using respin 20070401
2. Then do a yum upgrade (111 packages when I did it)
The original Steps to Reproduce is a bit misleading. Hope the above clarifies
what I did.
I'm not real sure this should be a kernel bug report. Maybe the udev program is
what is really causing the problem. The fact that the .20 kernel works fine with
FC-5 confuses me.
If somebody can tell me how to save all that status reporting after the crash
and submit it, I'd be only too happy to do so. There is a *bunch* of it! I just
included the first few lines.
We need the full backtrace. Take a picture of the screen with a digital
camera and post it as an attachment.

Try booting without the ide-scsi driver. Looks like error handling is
broken for that one and there should not be any need for it anyway.
Thank you for the advice. Could you tell me how to disable loading of the
ide-scsi driver? I really have no clue. The error readout shows it as a module
that is linked into the kernel, but I can't where the link might be.
ide-scsi is usually activated by a kernel command line option like:
Without that it shouldn't be used.
The entry for FC-6 in my /boot/grub/menu.lst shows the following line for the
kernel /boot/vmlinuz-2.6.20-1.2948.fc6 ro root=LABEL=/ vga=791
There is no hdh=ide-scsi. That used to be used for the Sony CD-RW burner.
Recent kernels apparently had it linked in "somehow"! I see in the error
printout that 'ide-scsi' in among the modules linked in.
Is there a way to unlink ide-scsi? Recompile the kernel? Gulp!
Thanks, Steve E.
I just tried to load Fedora 7. The installer crashes at the line "Loading SCSI
This plus the FC-6 problem is reminiscent of problems I had with the tape drive
and the (old) cd burner not playing together. They both need ide-scsi emulation.
My system has 7 ide devices. 4 are connected to the two master slave controllers
on the mobo, the remaining three to a pci-ide adapter card by Promise
Technologies. By carefully tweaking the locations of the tape drive and cd
burner in the ide chain, they both worked.
So as an experiment, I unplugged both the cd burner and tape drive. FC-6 with
the .20 kernel now works just fine. The F-7 installer also runs like a clock!
So these problems are traceable to hardware quirks in my system. However, I
still think there is a bug - up till the .20 kernel, (in FC-6) everything ran fine.
By the same token, my machine seems to be the only one with this problem. Google
searches on the web and Bugzilla searches turned up nothing. So maybe this
problem is not worth pursuing? Y'all call it.

I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.
I am CC'ing myself to this bug, however this version of Fedora is no longer
Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.
Thanks for using Fedora!
Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA,
