Summary: X hang at random while using GL app with mach64 with
"timeout waiting for buffers"
Product: DRI
Version: DRI CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: critical
Priority: medium
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Created an attachment (id=17831)
--> (http://bugs.freedesktop.org/attachment.cgi?id=17831)
The end of kern.log that seems to happen just before it hangs
I compiled mach64 drm module from git, libopengl and the dri xorg module (still
mach64).
After playing a little with an opengl app, the screen goes black and nothing
responds. The machine seems not completely hang, but X prevents any further
action but rebooting.
The kernel log ends with the following message:
Jul 23 07:55:04 chibchas kernel: [ 451.014390] [drm:mach64_freelist_get]
*ERROR* timeout waiting for buffers: ring head_addr: 0x50000e80 head: 928 tail:
1440
Jul 23 07:55:04 chibchas kernel: [ 451.014400]
[drm:mach64_dma_dispatch_vertex] *ERROR* couldn't get buffer
My dist/level is an unstable debian freshly dist-upgraded.
I use EXA.
The card is a "ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64)"
I'll try to give a X log.
