Hi, For info, my systems have just been updated with the kernel 2.6.32.16-141.fc12.i686.PAE. This is causing problems on two of them that have ATI Radeon cards. There are occasional Kernel OOPS followed by very slow graphics. The messages in /var/log/messages are: Jul 15 16:15:50 beam kernel: ------------[ cut here ]------------ Jul 15 16:15:50 beam kernel: WARNING: at drivers/gpu/drm/radeon/radeon_fence.c:159 radeon_fence_signaled+0x56/0x83 [radeon]() Jul 15 16:15:50 beam kernel: Hardware name: X5DA8 Jul 15 16:15:50 beam kernel: Querying an unemited fence : e73b9320 !
