Why and will this WU resume processing?

for WU: WT_S3F1_C3-SDOERR_BNBS-0-4-RND3170_1 (http://gpugrid.net/workunit.php?wuid=12213215)

I keep getting a strange error, despite having been running GPU for a couple of years now.

...I did just recently update the drivers; however, Milkyway gpu WUs are running just fine.

BTW, it is not, I don't believe, a matter of WUs interfering with each other.
Milkyway is using OpenCL.
When I suspend all Milkyway WUs, the same error still keeps coming up for GpuGrid

2016-12-20 4:53:19 PM | GPUGRID | task postponed 600.000000 sec: Waiting to acquire lock

In fact, when I suspend the Milkyway project, the same error still keeps coming up for GpuGrid

Other 'tidbits'
There seems to be no way to restart the task before the 10 min (600.0 sec) has lapsed.
This error always happens right at 30 sec into the task running, and
... each time I suspend other gpu tasks, WT_S3F1_C3-SDOERR_BNBS-0-4-RND3170_1 restarts from 0:00 time elapsed.

From the general experience of the users here, when any WU restarts at zero time elapsed and zero percent, that WU will either not validate correctly or will end in some error. When you see this happen, the best thing to do for the project and for your systems not wasting time, dump it and hope to get a new one... even in these tough times of getting new work.

Thanks.

PS I have deleted the WU, and am trying to get another one (:
So, when I get the next WU I guess for now I just have to keep 'my fingers crossed' that the problem does not recur.

Yes, deleting the task and getting a new one seems to have worked.
However, the question is STILL unanswered.
John C MacAlister posted this same problem--issue, a couple of years ago... and HE never got a real answer either (not on the boards).

The task stalled because you changed driver mid-run. It's recommended that you select no new work, suspend queued non-started GPUGrid tasks & finish running started tasks before changing drivers. What was the purpose of the driver update?
