Thank you for the testing and the report here!
Juno-r2:
- LTP controllers
- cgroup_fj_stress.sh
Test crash: cgroup_fj_stress_net_cls_1_200_one: [ 365.917504] /usr/local/bin/kirk[402]: cgroup_fj_stress_net_cls_1_200_one: start (command: cgroup_fj_stress.sh net_cls 1 200 one) [ 374.230110] ------------[ cut here ]------------ [ 374.230132] WARNING: lib/timerqueue.c:55 at timerqueue_del+0x68/0x70, CPU#5: swapper/5/0
This looks like we are removing a timer that was already removed from the queue.
I don't see anything obvious right away in the delta that would clue me into what's going on, but I'll try to reproduce this.
