I experienced the same problem with current a few months ago, with an
Intel ICH5 chipset and an 80Gb SATA drive.  I was virtually guaranteed a hard
lockup at least once a day during work hours and every morning I'd
arrive in to a frozen box.  There was no pattern to the lockups.

I "solved" the problem by moving to a non-SATA drive and removing the
SATA drive from the system.

Does anyone know the current status of ICH5 support?  I remember a number of
mails to the list about ICH5 issues, but don't remember if these were
ever addressed.
