commit 436e61d93605a3a36902c9ee510b0ecba0d7d361 Author: Ingo Molnar <mingo@elte.hu> Date: Tue Oct 16 23:18:38 2007 -0700
fix the softlockup watchdog to actually work ...
Causes my SMP niagara systems to trigger the softlockup message frequently when the nohz timer fires.
The backtrace is always in the timer handler, the cpu is not wedged at all, which makes me think it's likely triggering erroneously.
I suspect that what is happening is that the NOHZ period is longer than the softlockup timeout (10 seconds) and we get an interrupt before the watchdog thread gets onto the cpu.
I'll happily test any suggested fix for this bug, thanks! - 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/
