Hi
There seems to be some DRM problem with X.Org 6.8.0 on 2.6.8.1. I recently
switched from XFree86 and there I did not noticed the same thing.
System information: P4 2.8 Ghz HT, Intel 865G on-board graphics, ASUS
P4-P800VM mobo, having compiled preempt, SMP (for HT, which works) and SMT
scheduler.
It seems to happen when starting xdm/gdm.
ksymoops parsed kernel message:
mtrr: base(0xf0020000) is not aligned on a size(0x400000) boundary
[drm:i830_dma_initialize] *ERROR* can not find dma buffer map!
[drm:i830_irq_emit] *ERROR* i830_irq_emit called without lock held
Unable to handle kernel paging request at virtual address f000e2d3
