DRM debug output from foobillard crash

Am seeing X and sometimes entire system freezes when using various DRI  dependent apps including:

1. mplayer 

outputting via Xv [with DMAforXv enabled] results in X freezing for ~30sec, after which display is momentarily updated before feezing again. Keyboard & mouse are locked, but system responds to ACPI events. No feezing occurs if DMAforXv is disabled.


2. wine 

results in semi-random ~30sec X lockups after which X resume normal operations until next semi-random freeze. Strictly may not be a wine issue - something wine does initiates the problem, but it continues after all wine apps have been closed.


3. foobillard 

Usually results in complete system lockup.


With mplayer and wine I see the following repeated in my Xorg.0.log:

(EE) R128(0): R128CCEWaitForIdle: (DEBUG) CCE idle took i = 1025
(EE) R128(0): Idle timed out, resetting engine...

This bug has close cousins documented: <a href='http://bugs.freedesktop.org/show_bug.cgi?id=5562'>5562</a> and <a href='https://bugs.freedesktop.org/show_bug.cgi?id=3493'>3493</a>

After viewing these bugs, I've collected various logs including a DRM debug log, which I have attached.

Kernel log from about time of foobillard system lockup

DRM debug and this kernel log apply to the same foobillard system lockup (note the timestamps). Last line of this file is my futile attempt to reboot my system via ACPI...

Kernel log associated with mplayer+xv+dma X freeze

Not sure about exact timing of the error logged with respect to the X freeze - it might be before, at or after the time of the freeze. However it *is* associated in some way, as i don't see this unless X freezes due to mplayer usage.

Xorg log associated with wine semi-random X freezes

R128CCEWaitForIdle errors are near EOF. Log captured prior to addition of DMAforXv setting.

DRM debug output from foobillard crash

Am guessing that the repeated logging of "[drm:r128_freelist_get] returning NULL!" towards the DRM debug log EOF is significant. Perhaps the multiple calls to drm_lock near the beginning of this same log are too?

There's no longer an r128 DRI driver.
