Hi RT Devs, I enabled cpu/cpuacct/cpuset/devices/freezer subsystems in cgroup.
Attach serveral thread ids to these systems' tasks file frequently last 4 or 5 hours(start process, echo thread ids to tasks, stop process). The system will hung, no response to user keyboard input. Through I have enabled kdmp, but this scenario didn't trigger kdump. Pls help. Thanks
