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.

First of all, please send email using plain text mode. If you need to send picture, better attach it to somewhere else and provide us with the link. I am just guessing: it might be that when timer is about to run or in the middle of running, the data structure that represents the timer gets deleted. Sounds like race condition then. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
