[Dri-devel] Radeon DRI and recent CVS

[<dr...@ar...>]

Before I begin, see if any of the following sounds off red alerts:

New Tbird 1GHz
Abit KT7 (VIA chipset...)
Radeon 32 MB DDR
2.4.1 and 2.4.2-ac9 tried (2.4.2 plain had some serious issues w/ hard
  drive--WD)
DRI cvs from yesterday (maybe not exactly yesterday; I updated the
  tree today and there were no changes)

Apologies for the long message, but I want to pinpoint the problem
exactly:

Though I've forgotten the exact date, a CVS checkout from sometime
around January 15, 2001 worked with very few hitches, even with
Debian unstable's stock X server loading the DRI libraries (I have
since changed to using the X server compiled by the DRI tree). After
upgrading to the Tbird I did test DRI stuff some, but not extensively,
and everything seemed to work.

Then around February 28th (and again up through today), I updated to
the latest DRI CVS, and forgot to make a backup of my old tree
(OOPS!). The X tree compiled fine, installed fine, and the kernel
driver installed fine (yes I made sure it was the one from the DRI
tree and not the kernel). After loading Unreal Tournament (which
worked quite nicely before the change; around 30-40 FPS), however, I
am now able to play for 2-5 minutes, then the entire system freezes up
hard -- no telnet (well ssh...), no pings, no console. The monitor
usually goes blank, though sometimes the last displayed frame stays,
or it displays "Out of range".

I have gone through many pains to try to get any kind of log message
from the lockup, including remote logging on another machine, but not
serial console. (If this would greatly help I can try, but it won't be
easy.)

I was quick to blame Unreal or Mesa at first, but found that a similar
freeze would happen after some time in X without having run any 3D
programs, and I just checked that libGL is not mapped by any currently
loaded programs. X works fine when the kernel driver and agpgart are
not loaded, and in this condition I have played UT for over an hour
with software rendering with no problems.

Any ideas at all? Anything would be appreciated (software rendering,
even on a Tbird, just doesn't cut it; no more than 10 FPS and the
software renderer has some issues with its Z buffer and lighting). Or
do I have to go back to Windows for games (*shudders*)
