Hi,
I've encountered kernel panics on my P4 machine few times. These
panics only happened occasionally (like once every month). I'm not
sure if they are time dependent, but they seem to only happen around
5-7am in the morning. The only nfs server I'm running is cfsd, so
they may be cfs related.
Thanks,
Chi-Fung
