GPU giving Mutex lock error while peocessing einsteim@home WU

Hi there,
I'm running a linux system with Radeon/ATI 7750 card.

JUST in the last few weeks, I have been seeing this error in the /var/log/syslog file (From the GPU running the OpenCL driver)

Jun  6 14:01:24 pc-14-large kernel: [13330.559474] [fglrx:KAS_Mutex_Release] *ERROR* Mutex released without holding it.
Jun  6 14:01:24 pc-14-large kernel: [13330.746082] [fglrx:KAS_Mutex_Release] *ERROR* Mutex released without holding it.

Jun  6 14:15:35 pc-14-large kernel: [14179.673419] [fglrx:KAS_Mutex_Release] *ERROR* Mutex released without holding it.
Jun  6 14:16:07 pc-14-large kernel: [14212.460345] [fglrx:KAS_Mutex_Release] *ERROR* Mutex released without holding it.

The wu complete. I don't see any error reported to Einstein.

The time interval between errors decreases until the system crashes.

Question: Anyone else seeing this??

Here are my tasks:

I set "no new tasks" just to verify that the problem exists only when running GPU WU.

Here is what BOINC says about the system

Here is result of WU with the Mutax error above.
(I don't see any problem.):

Here is the WU:
http://einsteinathome.org/workunit/191675693

I have a radeon ATI card with 2GB of memory.
My Config is set to 1/1 - 1 whole PC and only 1 WU in the GPU.
I only work GPU for Einstein - No CPU tasks.

The CPU has 8 processors. They work on WCG and POGS.
CPU utilization is set to 75%
2 idle
1 to handle the load/unload of the Winstein GPU work
5 to handle WCG and POG WUs.

I use UbuntuStudio (Ubuntu 14.04) and use the 'restricted flgrx-updates driver provided by ubuntu.

Today, I put in the fglrx-updates-dev driver to see if there was any difference.
No difference. Still errors.

i A fglrx-amdcccle-updates          - Catalyst Control Center for the AMD graphi
i   fglrx-updates                   - Video driver for the AMD graphics accelera
i   fglrx-updates-dev               - Video driver for the AMD graphics accelera

Yes, this is a lot to read.
Sorry about that.
Wanted to cut down on "Can you get this info?".

:)

That said, Is there any other info I can get to help debug??

Other: Looking at the output. I did not see any checkpoints - so maybe that can be ruled out...

I'm stumped. I didn't see "mutex" in the forum search tool.

Logging needed?

Suggestions appreciated.

Thanks,
Jay

PS.
Just in case, I listed this problem in the AskUbuntu Forums

No suggestions there - yet.

Thanks again,
