When bonnie++ was run in a loop, the system exhibits a hang behavior with
"rcu_sched: self-detected stall on CPU"
The time to error can be inconsistent. One time it took 7 hours and the next time more than 2 days.
Commands to reproduce the failure:
$ sudo apt-get install bonnie++
$ mkdir bonnie
$ while true; do bonnie++ -d bonnie; done &>>bonnie0.log &

SRU Justification:
Impact: running a test like bonnie++ makes the system instable and prone to hangs.
Fix: apply the attached patches and recompile a kernel.
Test case: leave bonnie running in a loop for 24hrs.
--
When bonnie++ was run in a loop, the system exhibits a hang behavior with
"rcu_sched: self-detected stall on CPU"
The time to error can be inconsistent. One time it took 7 hours and the next time more than 2 days.
Commands to reproduce the failure:
$ sudo apt-get install bonnie++
$ mkdir bonnie
$ while true; do bonnie++ -d bonnie; done &>>bonnie0.log &
