radeon drm v1.21.0 freezes X.Org 6.9.0 with ATI FireGL Mobility T2
Last modified: 2006-07-29 03:08:04 UTC
New Radeon driver 1.21.0 from dri cvs freezes my X.Org R6.9.0.
Radeon 1.20.0 works with my IBM Laptop T42p fine, no lockups.
Adapter is M10 NT, ATI FireGL Mobility T2.
Machine is IBM Laptop, 2373-F4G
Linux Kernel 18.104.22.168.
I doubt the 1.21 changes should affect anything.. its more likely the
radeon_cp.c changes but I only added that for a few days and it broke more than
it fixed so I reverted it..
I fetched drm from cvs just now and nope, still freezes.
Some modification made 29.12.2005 did broke it, because i fetched 28.12.2005
version from cvs and it works ok.
Reverting the patch from radeon_cp.c rev. 1.71 fixes this bug for me.

Ouch, this is messy to fixup, as the fix that went in on Dec 16th wasn't correct
(i.e. lots of other systems broke with it).. so I assume your system never
worked before then?
Ben was working on patch but it'll take a while, there are a few areas to change...
Never worked before what date? I didn't use the Radeon DRI before 2005-12-23. Do
you want me to try the code from before 2005-12-16?
X.Org 6.9.0 just made its way into Debian/testing and I just got hit with this
bug (or what may be this bug). It seems to freeze the entire system (but no
kernel panic blinking lights) after about 3-10 minutes of running Xorg, even
from gdm. It seem particularly fond of freezing while drawing to the screen.
This is on a Thinkpad T42p, M10 NT FireGL Mobility T2.
Reproduced in both stock Debian kernels: 2.6.15, 2.6.12
Perhaps #4847 is related?
Please test Benjamin Herrenschmidt's memmap patches, current versions:
He posts updates to the xorg mailing list.
Not sure if this is related to #4324 but modular CVS HEAD stopped my X from
Just posting a "me too".
Radeon FireGL T2, ThinkPad T41p, Debian Testing, kernel 2.6.8 (Debian).
Upgrade to X.org 6.9 caused random freezes after a few minutes, or immediately
if I tried to run anything involving OpenGL. I've reverted to 6.8. (Same config
On the plus side, it was definitely much faster until it froze :-)
Any improvement using current xorg/dri?
This should been fix with current ati driver (r300 initializatio
fix) thus i am closing the bug. Reopen it if you still have this
issue with newest ati driver.
