So the warning in dmesg is gone of course, but the test (that I
mentioned in previous email) still fails, and this time it caused the
kernel to crash. In addition, now other tests fail as well, e.g.
KFDEventTest.SignalEvent
I honestly suggest to take some time to debug this patch-set on an
actual Kaveri machine and then re-send the patches.
Thanks,
Oded
