That was my first thought, too, but then he mentioned that the problem only occurs after a few hours of uptime, so it can't be a kernel/bin out-of-sync problem (which would be there right after booting). It definitely sounds like a hardware problem. Could be the disk (this is the first thing I would check), but it could also be a problem with the controller, maybe a temperature problem (maybe it gets too hot after a few hours). Checking the fans is certainly not a bad idea. As for the non-existing error messages indicating hard disk errors -- is syslogd running at all? Maybe it died just like ps and top. Try logging some stuff yourself, like "/usr/bin/logger foo bar" -- does it end up in the messages file? If not, can you "echo foo bar >> /var/log/messages"? If that causes I/O errors, too, then there's your reason.
