Red Hat Bugzilla – Bug 636326
After kernel update, screen goes blank during boot
Last modified: 2010-10-11 16:45:58 EDT
Description of problem:
I recently updated my kernel from kernel-18.104.22.168-12.fc14.x86_64 to kernel-22.214.171.124-28.fc14.x86_64. No other packages were updated at the time. The update resulted in the system's screen going black during boot. Adding "nomodeset" to the kernel's boot arguments fixed the problem, but resulting in sub-optimal video.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Upgrade to kernel-126.96.36.199-28.fc14.x86_64 and reboot.
The system is a MacBook 5,1 and uses the nouveau driver. Lspci reports, "02:00.0 VGA compatible controller: nVidia Corporation C79 [GeForce 9400M] (rev b1)."
Same problem with both kernel-188.8.131.52-28.fc14.x86_64 and kernel-184.108.40.206-29.fc14.x86_64. kernel-220.127.116.11-12.fc14.x86_64 is good.
~# lspci | grep VGA
02:00.0 VGA compatible controller: nVidia Corporation C78 [GeForce 9100] (rev a2)
Can boot with nomodeset parameter on the kernel line, but then can't use X with nouveau driver.

dmesg from last properly-working kernel (18.104.22.168-25.fc14.x86_64)
kernel-22.214.171.124-25.fc14.x86_64 boots properly.
kernel-126.96.36.199-26.fc14.x86_64 does not boot properly.
First entry in changelog for kernel-188.8.131.52-26.fc14.x86_64:
* Mon Sep 13 2010 Ben Skeggs <firstname.lastname@example.org> 184.108.40.206-27 - nouveau: fix oops in acpi edid support
Can't duplicate the good result I had earlier with kernel-220.127.116.11-25.fc14.x86_64 I just rebooted my desktop PC after having shut it off for several hours. However, kernel-18.104.22.168-12.fc14.x86_64 still works for me
Can you retry with: http://koji.fedoraproject.org/koji/taskinfo?taskID=2482757
Shut the desktop down for about 10 min, then rebooted using kernel-22.214.171.124-30.fc14.x86_64. Posting from that now, so I'd say it seems to work. Will report back if I encounter any problems after a longer shutdown
Everything seems to work properly after long (1 hr+) shutdowns. Problem appears to be fixed.
Thanks for letting us know :)

Seems fixed after I upgraded to kernel-2.6.36-0.32.rc6.git2.fc15.x86_64. I have been waiting for the next Fedora 14 kernel and will test it once it is available.
Michael, did you test the kernel Ben linked to above?
proposing as F14Blocker to make sure this fix doesn't slip through the cracks.
If it helps, I was seeing this also with the reported kernel on my macbook
02:00.0 VGA compatible controller: nVidia Corporation C79 [GeForce 9400M] (rev b1)
Using 126.96.36.199-30.fc14.x86_64, I no longer see the issue.
This was discussed and accepted as a blocker at the 2010-10-08 review meeting.
Ben / kernel team, it would be great if you could push all the stuff you want in F14 and come up with a proposed final kernel by Monday; that way we can have it in TC1 for testing.
kernel-188.8.131.52-30.fc14.x86_64 solves this issue for me.
-39 has been pushed stable, so let's close this.

Confirmed fixed in 184.108.40.206-39.fc14.x86_64.
