Hi All,
This question has to do with the Radeon 8800 drivers that ATI
just released. I know that they were written by ATI, but I have a question
that I believe is an DRI questions.
1) We have 15 identical machines each with a Radeon 8500.
Intermittently, DRI will fail with the following error in
/var/log/XFree86.0.log:
(EE) fglr200(0): [DRM] Failed to allocate texture sarea!
(EE) fglr200(0): [drm] failed to remove DRM signal handler
dmesg shows the following:

...
The systems have plenty of memory free:
total used free shared buffers cached
Mem: 1027860 213040 814820 72 57076 70460
-/+ buffers/cache: 85504 942356
Swap: 900088 0 900088
So.... Does anyone know why would "vmalloc" fail?
