Flagged bug as also effecting FC5T3; specificaly the bootable disks, I assume it
effects a proper installation aswell, but the bug kept me from properly booting
the install media to find out.

Comment 2 keifer miller 2006-03-11 16:32:34 UTC

Upgraded to kernel-2.6.15-1.1833 (on FC4), sadly, there was no change.

Comment 3 keifer miller 2006-03-18 16:26:30 UTC

It would appear that this may effect only first generation iMac g4's.

I discovered that this effects ubuntu's 2.6.15 kernel, and filed a bug report
there
(https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/34508).
I've also noticed that the problem is apperently resolved in suse's 2.6.16
kernel, so this was either fixed upstream, or by suse.

can you try the latest fc5 builds from my people page at
http://people.redhat.com/davej/kernels/Fedora/ ?

Comment 5 keifer miller 2006-03-20 01:13:24 UTC

I don't currently have a fedora install (will be reinstalled over suse 
sometime tonight); but I did drop the FC5 kernel in over the suse one, and it 
dies in exactly the same way as it was before (Monitor turns off, etc), so I'm 
guessing it wasn't fixed. 
 
Hopefully by tomorrow, I will have installed FC4, yumed up to FC5T3, and 
dropped in the new kernel; but I'm not hopeful on it working.

Comment 6 keifer miller 2006-03-20 19:52:00 UTC

I wasn't able to upgrade my FC4 install to FC5, but I did try the kernel, and it
died the same way as the others did.
