If you are using a 2.4.x kernel, I suspect it's something to do with VM.
I've had total lockups about once a day with this series, always when
using the modem and X. It isn't hardware because since reverting to
2.2.20 I've had no problems. I don't use modules so it isn't that and
there were few other processes running at the time. No particular
browser or other program appears to cause it reproducibly.
On my laptop (Toshiba Satellite 4000CDT) I use 2.4.16 without any
lockups.
