[Bug 230544] Re: Computer lockup and screen full of garbage [i82810E DC-133]

[Simon Iremonger]

I'm getting a similar error but different problem ;-).

All worked fine on Ubuntu 8.04 LTS (actually I think I got warnings in
the dmesg, but it all still *worked*).

This machine has:-
00:02.0 VGA compatible controller: Intel Corporation 82815 Chipset Graphics Controller (CGC) (rev 04)

Under Ubuntu 8.10 -- even with a 'new' default xorg.conf -- all works fine on a single X-server...
But as soon as I start a second X-server *using gdm / 'switch user'* it won't start, and I get similar errors in dmesg:-

[41900.203101] mtrr: base(0xf8000000) is not aligned on a size(0x3000000) boundary
[41933.640735] mtrr: no MTRR for f8000000,3000000 found
[41949.696017] [drm:drm_release] *ERROR* reclaim_buffers_locked() deadlock. Please rework this
[41949.696027]  driver to use reclaim_buffers_idlelocked() instead.
[41949.696030]  I will go on reclaiming the buffers anyway.
[41952.700010] [drm:i810_wait_ring] *ERROR* space: 65520 wanted 65528
[41952.700018] [drm:i810_wait_ring] *ERROR* lockup
[41955.756017] [drm:drm_release] *ERROR* reclaim_buffers_locked() deadlock. Please rework this
[41955.756026]  driver to use reclaim_buffers_idlelocked() instead.
[41955.756029]  I will go on reclaiming the buffers anyway.

The funny thing is, if I switch away from X server and start one
manually, that works (but with no DRI)... I wonder what's going on!!!
