[Dri-users] screen hangs with G450 and certain 3D apps

[Carl W. S. <ch...@re...>]

I've been trying to get 3D rendering working with my G450; and while I
finally got Direct Rendering Infrastructure working, I'm getting repeatable
console hangs with some games that use 3D rendering. :(

fgfs (flight simulator), and atlantis (the swimming whales demo) don't seem
to cause it; but when I play Rune (the Loki Linux port), or Half-Life (under
wine), it will lock up the console after a minute or two.

someone on #dri (on irc.openprojects.net) suggested building a kernel
without framebuffer support; but this didn't help.

anyone have any suggestions what to do, or at least how to debug this?
I tried 'strace rune 2>rune.strace'; and it ended up spewing 116MB before
Rune hung the screen, and I killed the process. the process was still going
after the screen hung; so I had to ssh in and kill it. I first tried killing
it with -15; but when that didn't work, did a -9 on it.
here's the output of the strace, at the point where it stops being
interesting:
