This is reproducible. XFCE Desktop > Applications > Preferences > Screensaver; Random screensaver (leave default selections checked), Blank after 2 minutes, Cycle after 1 minute; Advanced tab > Power saver off (want screensaver to loop forever, trying a random screensaver once per minute); File > Blank now. Wait; in this particular case, 7 minutes.

BUG: Unable to handle kernel paging request at fffffffc
Added [Redwood][RV280] tags adjacent to [RV200] in Summary, reflecting Comment #6 and Comment #7. Such a wide range of cards suggests that the bug is in [ttm] independent of which card, particularly because one common feature is low kernel RAM (1023m of Comment #6.) I've built a scratch kernel at it will end up at: http://kojipkgs.fedoraproject.org/scratch/airlied/task_3098801/ it should be finished in a few hours, though it may disappear in a few days. Good news: kernel-2.6.38.7-30.bz680651.fc15.i686 survived 110 minutes [normal termination and no OOPS] running xscreensaver under XFCE on a 1GB machine with RV280 (PCI 1002:5960:174b:0130).

Fixed in 2.6.38.8-31 *** Bug 716495 has been marked as a duplicate of this bug. *** |
