Thank you for your quick response.

> And BTW, what does the failure look like?

For the record,

Environment:
  linux 3.2 / 32bit arm kernel / CONFIG_RT_GROUP_SCHED=n

Commands and outputs with crash-7.0.9:

crash> task -R on_rq,sched_class 35
PID: 35 ...
  on_rq = 1,
  sched_class = 0xc027df80 <rt_sched_class>,

crash> runq
CPU 0 RUNQUEUE ...
  ...
  RT PRIO_ARRAY: c0bf238
    [no tasks queued]

Patched crash displayed task 35 on RT PRIO_ARRAY.

Thanks!
