I built from mainline HEAD, currently 4.19rc4.r209.g10dc890d4228, and was able to reproduce the bug before any code changes. Stack trace from the one test is attached. I then rebuilt with the above line changed, but the problem continues. Stack traces from two tests are attached. First one was a null pointer deref instead of general protection fault, but I have seen that beforeas well. I have noticed that with this newer kernel version (with and without code change), the crash does not always happen immediately after starting tvheadend. A few times, I have been able to tune in a channel and watch for a few seconds. Then the crash would happen after flipping through 3 or 4 channels. > > > > > Also, it would be great if you could post the GPF logs. > > It's difficult to capture much, since the system often locks up > without > syncing to disk.
