[v4.9-rt][report] stress-ng: possible circular locking dependency detected

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
