Question is: who is holding interrupts off for so long?
It might be better to implement a detection scheme inside the timer interrupt handler: if the time since last interrupt exceeds two ticks, whine and drop a backtrace.
That backtrace will point up into the local_irq_enable() in the offending code, and we can go fix it? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
