drm module built using the most recent (13:30 07/07/2006) CVS as well as most 
recen git for dri module.

After X startup, in dmesg I can see:

manager.

When I enable irqpoll option system hangs hard on X startup (I can't get any 
message, all I can do is hold power button for >4s).

Upgrade to latest Openchrome SVN. The bug is fixed there.
I will pull it into xf86-video-via when I get time.

This is a hardware bug, present on all K8M/N800s and some KM/N400s. Use the 2D
driver option "DisableIRQ".

Accidently closed the bug...

Comment 3 Michał Pytasz 2006-07-08 13:27:43 UTC

Ok, thanks it seems to solve this problem, yet I have another with unstability
of xorg using OpenGL in Webots robot simulator. Should I add comments here or
rather open another bug?

It's a well known problem that K8M/N800 hangs the system when using textures,
for example with Mesa demos "fire" or "ppracer".

There's already a bugzilla bug for this.
AFAIK, there's no workaround for that available, and ATM no Unichrome 3D driver
maintainer.
