Subject: [v4.9-rt][report] stress-ng: possible circular locking dependency
detected
Hi All,
I've tried to run stress-ng on TI am57xx-evm (SMP, 2 cpu) and caught 2 "INFO: possible circular locking dependency detected"
Command 1 (log 1):
## stress-ng --class cpu --all 0 -t 5m & stress-ng --class memory --all 0 --vm-bytes 90% -t 5m
Command 2 (log 2):
## stress-ng --class os --all 0 -t 5m
actually command 2 often stuck or crushes (Log3 - I've collected 3 different dumps)
--
regards,
-grygorii
