Can you update to kernel 2.6.31-23.fc12 and retry please, this should be fixed.

Comment 3 Adam Williamson 2009-09-17 20:29:35 UTC
if it's not convenient for you to do a rawhide install, you can get nightly live builds here:


probably tomorrow's will have a new enough kernel.

ben, best to set to MODIFIED if you think it's fixed, rather than NEEDINFO.

Thanks! a nightly live image is definitely preferable as I can't really re-install the machine.

Comment 5 Ben Skeggs 2009-09-25 08:24:01 UTC
Have you had a change to test a later snapshot?

Comment 6 Mike Gahagan 2009-09-25 14:37:00 UTC
I'm having problems getting yesterday's USB live image to boot (using the desktop x86_64 nightly).. I'll give it a try once I can get past that or find another working live image.

Comment 7 Adam Williamson 2009-09-25 15:55:13 UTC
note that nightly builds from 20090918 to 20090923 were broken (failed to boot) but from 20090924 onwards should be OK again.

I tested desktop-x86_64-20090927.16.iso as a USB live image using the fast user switch and vtswitch testcases, no lock-ups and no display corruption evident after switching between users/vt's for about 5 minutes. I noticed some delay initially in bringing up the login screen, but that dissapeared after the first few times so mostly likely due to slow USB I/O and the buffer cache not yet primed.
