Hi!
I have Radeon8500LE 128MB AGP successfully running under Fedora Rawhide and DRI
is working, but I
tried Doom3 and it freezes at loading screen.
I understand that priorities may have shifted to get R5xx-R7xx cards into 3D,
but until new DRI/DRM
bits arrives, this issue probably affects all radeon users, as we share single
drm module.
radeon_freelist_get() comment also indicates it could be improved :)
According to KGDB and OProfile it loops forever in
radeon_cp_texture/radeon_freelist_get:

Dmesg is full of radeon_freelist_get, but radeon_cp_dispatch_texture shows only
once (not sure)

strace cannot be attached, so I assume process never leaves kernel space. It
can be killed with -9,
but it all ends up with Xorg consuming 100% CPU and kernel Oops.
Changing FBTexPercent and GARTSize has no effect on this lockup. EnablePageFlip
is stable on this box.

The kernel is 2.6.29-0.119.rc5.fc11.i586 SMP, and the system is AthlonXP 3200+
VIA KT880.
Latest released X.org, Mesa, and xf86-video-ati (whatever is currently in
Rawhide).
Sauerbraten FPS is stable and fast. Extreme Tuxracer also works, but slow - 85%
in copy_from_user().
Is there something that can be done to fix the issue? I'm commited to provide
the feedback in case
more information, testing and patching is required.
