Deadlock in backend since latest .25-fixes update.

As indicated in the title, I am currently experiencing deadlocks in the backend as below:

I am on the latest .25-fixes built for mythbuntu: 2:0.25.0+fixes.20120703.1282eb3

Prior to doing the updates yesterday, I had never had this problem. My last update prior yesterday was around middle of last week.

Regards, and Help!

I'm experiencing the same unresponsiveness and error messages (about
once every 2 days). My backend is slightly older:

MythTV Version : v0.25.1-49-g65913e7
MythTV Branch : fixes/0.25
Network Protocol : 72
Library API : 0.25.20120506-1
QT Version : 4.7.4

I just upgraded to mythtv-backend
2:0.25.0+fixes.20120703.1282eb3-0ubuntu0mythbuntu3. We'll see if this
makes any difference. One of the backend lockups occurred when I was
using the frontend, just after finishing watching a recording. A
recording was in progress, but no reschedule was requested, so not
sure if this fix is relevant:

Additional information:

Restarting the mythbackend service doesn't correct the problem. Also, I tried stopping mythbackend, stopping mysql, then starting mysql and mythbackend, and no luck.

Rebooting did fix it, though I don't know why it would and not restarting the above services.

My previous version was 5b843c12.

I have seen 3 deadlocks, since upgrading. Looks like it might be the culprit..

I have to reboot the backend to fix it.

I would say it's the scheduler deadlock issue that's currently
"testing" in trunk to be included in 0.25-fixes, but the fact that
killing the backend process alone doesn't fix it, requiring a reboot,
makes me think otherwise as that works for me.

Perhaps a hardware/driver issue if a reboot is required?
