I made some further investigations for the nouveau driver today. Kernels 3.5.0-10 to 3.5.0-12: The issue is present with a corrupted screen and massive logging of PFIFO_CACHE_ERROR messages.
Kernel 3.5.0-13 The issue seems gone, i.e the nouveau driver again! It seems that the fixes for kernel 3.5.0-13 (two bugs) also fixed this issue! My guess is the framebuffer recycling issue being fixed. The issue also is present in kernel 3.6, but never mind as 3.5 will be shipped for Quantal. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1039125 Title: [drm] nouveau 0000:02:00.0: PFIFO_CACHE_ERROR - Ch 2/2 Mthd 0x0800 Data 0x00000000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1039125/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
