That's just the backtrace which is not really helpful. The real question is
what leads to this scenaria.

What I was asking for is to enable the irq_vector and irq_matrix trace
points along with ftrace_dump_on_oops. The latter dumps the trace buffer
when the problem happens and that should give us a hint what actually
causes that.

Thanks,
