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 (i.e. in check_hung_task() function).

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
