Why does kernel.hung_task_panic = 1 not trigger a system panic in RHEL?
Issue
- Since there has been hung_task_timeout_secs for a while, kernel.hung_task_panic is set to 1 by administrator.
- However kernel.hung_task_panic = 1 does not trigger panic and does not show hung_task_timeout_secs.
Environment
