Upgrade to latest Openchrome SVN. The bug is fixed there. I will pull it into xf86-video-via when I get time. > irq 22: nobody cared (try booting with the "irqpoll" option) > [<c013a767>] __report_bad_irq+0x2b/0x69 > [<c013a978>] note_interrupt+0x1d3/0x203 > [<c013a275>] handle_IRQ_event+0x22/0x4e > [<c013a330>] __do_IRQ+0x8f/0xcf > [<c0104b49>] do_IRQ+0x19/0x24 > [<c010354e>] common_interrupt+0x1a/0x20 > handlers: > [<dd07a3cf>] (via_driver_irq_handler+0x0/0x147 [via]) > Disabling IRQ #22 > > 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). This is a hardware bug, present on all K8M/N800s and some KM/N400s. Use the 2D driver option "DisableIRQ". /Thomas
Accidently closed the bug...
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?

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. /Thomas
