From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030103 Description of problem: I wanted to install phoebe2 but i couldn't. It booted fine from the first CD and then I did a mediacheck test and all 3 CDs passed it. Then I inserted the first CD again and it didn't go further to the graphical installation screen. This also happens when I skip mediacheck test and install immediately. I looked on the tty3 and it stops when loading modules: reiserfs, xfs, lvm-?, ... On the tty4 it keeps saying wrong cdrom iso9660 format (i don't remember the exact words) and than it says ATAPI restart completed (or something similar). If you need exact words I can reproduce this again and write down the messages. I use a plextor cdrw 241040ta which is connected as the master on the secondary ide chanel (hdc). I installed all the previous releases (including psyche and phoebe1) without problems and my hardware hasn't change since then. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. boot off the first cd 2. press enter (for graphical install) 3. problem is 'here' Actual Results: install hangs and I have to do a hard reset Expected Results: install should proceed to the graphical install Additional info:
This sounds like a bad CD. Sometimes a CD can manage to pass the mediacheck and then fail later. I would recommend trying the CDs on a different machine and see if it can install from them as a sanity check.
As you suggested I did a sanity check and the CD works ok on the other computers. Additionally I wrote down the exact words about the error on tty4 Here they are: .... <7>ISO 9660 Extentions: RRIP_1991A <4>Unable to identify CD-ROM format <4>VFS: Can't find ext2 filesystem on dev loop(7,0) (the above lines are also the same on the machines that worked with this CD!?) <4>hdc: irq timeout: status=0xd0 {Busy} <4>hdc: irq timeout: error=0xd0LastFailedSense 0xd0 <4>hdc: ATAPI reset complete The last three lines keep repeating and eventually I have to press ctrl-alt-delete. Hope that helps. Tadej
Does it work better if you boot with 'linux ide=nodma'?
I figured out the problem. It is a really strange one. As I said, the original CD1 didn't work on my testing computer, however, it worked fine on other computers. I was really frustrated and I downloaded the first image again and burned it on another CD (same brand of CDR - BenQ). I burned the new CD with the same burner (Plextor 241040TA). This burner is also used for reading the CDs during installation on my testing machine. And the new CD worked! So my wild guess is that the burner on my testing machine was more sensitive to reading 'scratched' or somehow 'bad' CDs than the normal cd-roms on the other machines that I used as a sanity check. But how did it (the bad CD) pass the MD5SUM check at the begining of the installation and then failed later? I guess this is still a mystery.
The md5sum test in the loader is not guaranteed to catch all errors. The installation accesses the CD in a different pattern that the md5sum test (which accesses it sequentially). I've thought about trying to make the test more stringent but have not had time. *** This bug has been marked as a duplicate of 75008 ***
