The sysctl setting kernel.hung_task_verbosity is available since kernel 042stab056.2.
It controls what to show when kernel reports about a hung task (check_hung_task()).
The following bits are defined:
| Value | SysRQ key | Description |
|---|---|---|
| 1 | sysrq-p | CPUs |
| 2 | sysrq-t | Tasks |
| 4 | sysrq-m | Memory |
| 8 | sysrq-a | Scheduler |
| 0 | - | Nothing (this is the default) |
| -1 | - | Everything |
