BTW, why NMI watchdog is disabled by default?
There was a significantly large string of reports of dying PCs in the
2.4.early timeframe. These machines would mysteriously lock up after
considerable periods of time and the problem was cured by disabling the NMI
watchdog. Nobody was ever able to solve it, so we changed it to default to
off.
So much has changed in there that we might have fixed it by accident, and II attached the patch which turns NMI watchdog on by default on i386.
do recall a couple of fundamental and subtle NMI bugs being fixed. So
yeah, it might be worth enabling it by default again. Care to send a patch
which does that?
