Btw, this bug is very strange. So I did a couple more s2disk runs, i.e. echo "shutdown" > /sys/power/disk echo "disk" > /sys/power/state and it seemed to me that when the eth cable is plugged in, it would suspend and resume fine. When I then boot, unplug the cable, set all tunables to "Good", suspend to disk and resume, no NMI message. When I plug the cable back, only *then* the message triggered. I need to play with this a bit more to get a better sense of when exactly it happens. Thanks. -- Regards/Gruss, Boris. Sent from a fat crate under my desk. Formatting is fine. --
