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?
