I also need help.
First I thought the problem was a driver for my wireless network card (WUSB11 - at503a), but I switched to a wired card with a different driver and I have the same problem.
Most of my prgrams seem to run fine, but once I load OpenOffice (and I think either Gaim or Galeon at the same time) everything freezes. After 5 minutes or so the freeze will go away and then becomes intermittent.
I notice a message about unknown keyboard scan codes (I suspect my m!cro$oft keyboard with superfluous function keys to be the culprit) and spurious IRQ 7? I think it was.
I don't know what nfsd is, but I'll try killing it, if it exists, to see what the problem is.
