The sysctl setting <code>kernel.hung_task_verbosity</code> is available since kernel 042stab056.2.
It controls what to show when kernel reports about a hung task (<code>check_hung_task()</code>).

The following bits are defined:
{| class="wikitable"
! 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
|}
