Confirmed here. It was a lot more stable before -- but after I upgraded my
radeon driver and xorg-server (and possibly the kernel), it crashes pretty much
every time I play q3 (urbanterror), usually within a few minutes.

I just bumped into this while playing Quake Live. Since it runs through Firefox
(and it's variants), the crash takes the browser with it - which isn't nice.

I think there's some inefficiency in a way r300_dri.so
frees memory, compared to swrast_dri.so.

With 2.6.33-rc3, the problem still exists but the crash error is slightly more
descriptive :s..

"drmRadeonCmdBuffer: -12. Kernel failed to parse or rejected command stream.
See dmesg for more info."

(P.S. If I run the offending program from an xterm, for example, by the way, it
also crashes the xterm window and I have to kill it.)

Here's an example of it on a debian system. There are more mentions on some

--- Comment #20 from Dennis Nezic <dennisn@...>  2010-01-25 09:33:39 PST ---
That bug report referenced in Comment #17 suggests that downgrading mesa gets
rid of the bug, I tried compiling many many git snapshots from the current
2010-Jan "1.5 Mesa 7.8-devel" all the way back to 2008-Dec "1.3 Mesa
7.3-devel", and all the builds had this bug. (I'm not sure if I can compile
versions much older than that -- they complain about something regarding
swrast.) So, I don't think it's a mesa problem.

I also have problems compiling older versions of xf86-video-ati  :|.

Do the developers not have this bug? (I find the more graphics-intensive the
opengl ap, like a huge q3 map, the sooner / more likely it will crash.)

--- Comment #21 from Pauli <suokkos@...>  2010-01-27 02:40:42 PST ---
Problem here is kernel part of radeon driver which tries to allocate more than
one continues memory page which gets very hard under memory presure. So fix
should go to kernel that it allocates only single non-continues memory pages.

Possible work arounds for users are:

1. Free all possible memory so kernel has enough continues free pages for
radeon driver.

2. Downgrade kernel to 2.6.29(?). I'm not exactly sure if that was the last
version which used old kernel driver without this bug.

Unless we're lucky and it's only this commit, that creates problems:

Due to KMS migration, it's really hard to tell, what could be 
the real reason, as this is one of the dirs with most of the changes.

While comment 21 sounds like the real reason,
neither 1. nor 2. seems a good solution.
1. doesn't solve anything and kernel downgrade
seems a bad idea.

However if that the real problem, what are the chances of getting
it fixed by 2.6.34 (as 2.6.33 is probably out of the question now) ?

Sorry for the noise: comment 23 was a silly idea
- that commit is probably off-topic here.

Created an attachment (id=32899)

Possible fix. Only tested with r200 card!

Attached patch applies to current development kernel from Linus' tree
(2.6.33-rc5 should work too).

If you know how to compile your own kernel you can apply that patch to vanila
kernel source and tes if it fixes problems for you. But notice that this only
affects old kernel driver code and new KMS code is not changed anyway. If you
have same dmesg error messange with KMS it is different bug.

I tested patch shortly with r200 card (radeon 9200). Sauerbraten and compiz did
run without crashing.

IMPORTANT: I can't test r300-r500 (radeon 9500-x1950) code path so you must be
extra carefull with those cards. Kernel might crash or corrupt memory if there
is any hiden bugs which may destroy your data or eat your pet. But if you are
still willing to test with one those cards I'm happy to hear about any errors
you might see.

(In reply to comment #25)

Well, it's r300 for me and that comment makes me
oh-so-confident.

Could somebody verify the correctness of that code for my model ?

I tested this possible fix and first of all: it seems to work now, at least I
haven't experienced any problems yet.

More information:
I have here a radeon 9600 Mobility .. this is some sort of r300.

The kernel I patched is the SuSe Kernel of 11.2 -- this is some 2.6.31 with
those Suse patches applied -- and this patch applied cleanly (just some
hunks..)

I rebuilt only the radeon module and as it seems it works now for me!

Thx for the patch, now the occasional Urban Terror game is enjoyable again!

So I went and tested that patch.
No luck, right at the start:
[drm:r300_do_cp_cmdbuf] *ERROR* bad cmd_type 0 at byte 1220
in the syslog and app goes bye-bye.

Thanks for testing.

Can you reproduce the bug? If yes then booting with drm.debug=1 kernel
parameter and providing dmesg log showing what is going wrong in command
stream parsing would help fixing the bug.

PS. The patch affects drm.ko and radeon.ko so both of them has to be
installed if you only build the module instead of the full kernel.

Im sorry, your patch also doesn't work for me -- i see the same error as Rafał
now.
I hadn't checked before if the correct kernel module was loaded.

So now I have rebuilt and loaded the correct modules drm.ko and radeon.ko, and
the problem is simply reproduceable by running glxgears for instance.

To help you debug I loaded the drm module with debug=1 and got the log which I
will attach. Note: After loading this module produces a lot of debug messages,
I skipped a lot of the standard messages in the beginning, and the log stops
with the error, that appears when running glxgears (Nothing interesting happens
after that ...).

If I can provide more infos, I would be glad to help.

Log produced by drm.debug=1

This log shows the messages produced by the patched drm and radeon modules.
The log ends with the error that occurs when running "glxgears".

Second try to fix the memory allocation. Still needs r300 testing.

Thanks for log. It helped locating the error. I hadn't conerted the old
OUT_RING_TABLE to new OUT_RING_CMD_BUFFER macro. 

I also reviewed the changes again and found another bug too which fixed in this
patch too.
