| |
Hi everybody!
Since about July I observe occasional kernel panics happening only during system shutdown on two systems.
Hardware: mobos: both AOpen i915GMm-hfs mobos, cpus: Pentium-M Dothan / Banias, mem: 2GB Although the stack traces differ, there is one thing in common: CS:EIP is in run_timer_softirq().
A first report was posted to lkml on 2013-07-10: http://www.gossamer-threads.com/lists/linux/kernel/1744892?#1744892 jpg of the stack trace: http://www.gossamer-threads.com/lists/engine?do=post_attachment;postatt_id=57017;list=linux
There were several reports of kernel panics with run_timer_softirq() in the call_trace.
@Grant: You reported a kernel panic during shutdown for kernel 3.7.5, but the jpg is not accessible. Could you please verify if your report is related?
The problem is still present in yesterdays git master, see attached stacktrace. A shortened transcription of that stacktrace:
Bug: unable to handle kernel paging request at ... [...] Call Trace: __do_softirq+[...] irq_exit+[...] smp_apic_timer_interrupt+[...] apic_timer_interrupt+[...] ?default_idle+[...] ?clocksource_mark_unstable+[...] ?default_idle+[...] arch_cpu_idle+[...] cpu_startup_entry+[...] rest_init+[...] start_kernel+[...] i386_start_kernel+[...] [...] EIP: run_timer_softirq+[...] Kernel panic panic - not syncing: Fatal exception in interrupt
Any idea how to debug that problem? Insert some debugging code and constantly rebooting one of the machines would be an option, but I don´t have a clue what to insert ....
