Watchdog: break timeout loop via system fatal crash
Request system fatal crash via SysRq when a watchdog timeout loop is
detected. This escapes automatically the device hanging symptom and also
preserves context of system server in memory snapshot.
More details and background: go/break-sys-watchdog-loop
Bug: 141948707
Test: Insert 'sleep_forever()' to block BinderThreadMonitor to reproduce
watchdog timeout.
