[Crash-utility] timer: invalid list entry: 1

[paawan oza]

 I would give some more info.

It is dual core system.  (ARM)
both core are stuck at wfi (wait for interrupt)
and we observe that the timer counter has one much ahead than the comparators.
so we never get a local timer interrupt, and nobody is there to wake the cpu up.


so we observe the freeze.

Regards,
Oza.

It's impossible to answer without knowing the specifics.

It could be corruption, or perhaps the cpu 0 was manipulating
the timer chains when the kernel panicked, or perhaps there
is some off-the-wall condition that the crash utility has
never encountered.
