Just to be clear, you stated:
crash -d1 shows me crash: get_netdump_panic_task: crashing_cpu: 1 crash: get_netdump_panic_task: failed crash: get_active_set_panic_task: failed
and I presumed:
Now, since after the "crash: get_active_set_panic_task: failed" message, there are no more error messages, so panic_search() must have determined that the idle thread (swapper) on cpu 0 was in fact the running task that took the sysrq.
But, are there any other error messages after the
"get_active_set_panic_task: failed"? Like for
example:
crash: panic_search: failed (via foreach bt)
crash: get_panic_context: panic task not found
or did you see:
crash: panic_search: ffffffff80335340 (via foreach bt)
Thanks,
Dave
