Description Mads Kiilerich 2008-10-06 09:42:50 UTC
Description of problem:

System works, but when running glxgears or enabling compiz then it crashes short time after.

Kernel messages like these are logged:
[drm:radeon_cp_dispatch_texture] *ERROR* EFAULT on pad, 45056 bytes

[drm:radeon_mem_init_heap] *ERROR* heap already initialized?
mtrr: base(0xc49b6000) is not aligned on a size(0xb13000) boundary

Version-Release number of selected component (if applicable):


Same system as in bug 465331, but compiz works and nomodeset seems to not be needed anymore.

How reproducible:

yes, on my machine

Comment 1 Mads Kiilerich 2008-10-06 09:50:40 UTC
By "crashing" I mean "it hangs". Mouse can move, but keyboard (and capslock) doesn't work.

I can ssh to the machine and see the following top:

 2777 root      20   0  155m  28m 7724 R 175.6  1.4   3:36.97 Xorg
 2558 root      20   0  3624 1036  916 D 81.1  0.1   2:01.99 hald-addon-stor

Comment 2 Hans Ulrich Niedermann 2008-10-12 23:44:15 UTC
Is this issue still appearing with 2.6.27-2.fc10 or later?

Comment 3 Mads Kiilerich 2008-10-13 11:12:17 UTC
I was just about to report back that Desktop Effects worked and glxgears worked fine. (Glxgears did however use a lot of cpu - I thought that it would use hardware acceleration ... but the card/driver has perhaps only 2d acceleration ... never mind.)

BUT then it hang again, just like before.

kernel-2.6.27-3.fc10.i686 with nomodeset

strace shows that xorg loops doing
--- SIGALRM (Alarm clock) @ 0 (0) ---
sigreturn()                             = ? (mask now [])
ioctl(11, 0xc0286429, 0xbfa8ba74)       = -1 EBUSY (Device or resource busy)
--- SIGALRM (Alarm clock) @ 0 (0) ---
sigreturn()                             = ? (mask now [])
ioctl(11, 0xc0286429, 0xbfa8ba74)       = -1 EBUSY (Device or resource busy)

lrwx------ 1 root root 64 2008-10-13 12:51 /proc/3181/fd/11 -> /dev/dri/card0

And the kernel has two reports of
Oct 13 12:42:20 dev-mk kernel: [drm:radeon_cp_dispatch_texture] *ERROR* EFAULT on pad, 36864 bytes
and 30 of
Oct 13 12:42:21 dev-mk kernel: [drm:radeon_cp_dispatch_texture] *ERROR* EFAULT on pad, 45056 bytes

Nothing interesting in X logs.

(By the way: Is there a good way to start X in "safe mode" so that Desktop Effects isn't started even tough it is configured?)

Comment 4 Mads Kiilerich 2008-10-14 12:22:04 UTC
Actually, this bug is with radeon_drv.so, just like bug 466437. Sorry for the confusion.

And to make it clear: compiz "works" for half a second, then the system hangs.

Comment 5 Mads Kiilerich 2008-10-23 12:49:03 UTC
running without nomodeset

I just got
Oct 23 14:43:56 dev-mk kernel: [drm:radeon_mem_init_heap] *ERROR* heap already initialized?
Oct 23 14:43:56 dev-mk kernel: mtrr: base(0xc2875000) is not aligned on a size(0xb13000) boundary
Oct 23 14:44:07 dev-mk acpid: client connected from 2619[0:0]
Oct 23 14:44:15 dev-mk kernel: mtrr: base(0xc18b4000) is not aligned on a size(0x6ec000) boundary

It might be related to that I was testing fast user switching around that time.

Comment 6 Mads Kiilerich 2008-10-23 12:50:33 UTC
Re comment #5: I forgot to mention that AFAIK I was NOT using desktop effects or other GL stuff.
