Hi,

  In my x86 laptop I could observe random panic with Fatal exception in interrupt. We are testing Wi-Fi with our own driver issue occur randomly after 2-3 hours of testing.

  Panic is due to fatal except in interrupt and Kernel stack trace is  run_timer_softirq()->__run_timers()->cascade()->BUG_ON(tbase_get_base(timer->base) != base);

  Any pointers to debug this will be of great help.
