Description of problem:
During Nouveau Test Day, the suspend test [https://fedoraproject.org/wiki/QA:Testcase_nouveau_suspend] failed. Suspension occurred as expected, however resuming resulted in a stable white screen with the bottom 15% flashing black ~20Hz.
Version-Release number of selected component (if applicable):
(as on http://adamwill.fedorapeople.org/20090909_test_day_images/testday-20090909-x86_64.iso and during Nouveau Test Day)
Steps to Reproduce:
1. boot above ISO
2. suspend system
3. resume system

Are you able to provide some log files? /var/log/messages would be useful to see from after an attempted suspend.
Hi Brian - thanks for asking! /var/log/messages and Xorg.0.log from after a suspend+resume cycle aren't so telling, though we do see nouveau reprogramming registers - it's clear some registers either aren't restored correctly or are programmed with incorrect values likely, since the issue is 100% reproducible.
In this situation, I can switch to a non-X VT and get a blank screen (backlight enabled) and switching back to X resumes the white w/ bottom 10-15% flashing @ ~20Hz.
What would help here, eg dumping the GPU's LVDS register before and after the suspend-resume cycle?

setting this as 'triaged' as only Ben knows what info he needs from you :)

Can you retry with at least kernel-184.108.40.206-56.fc12 please? There's been some fixes to LVDS resume on pre-G80 chipsets since the kernel you tested. Thanks.
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.
More information and reason for this action is here:
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
