>Description:
      Randomly, the system will lock up completely, requiring a hard reset. If I'm in a terminal I'll see the message, "TIMEOUT - ATA READ /dev/ad6" or something like that, with an LBA address at the end. That line is followed by "TIMEOUT - ATA WRITE /dev/ad6" and a different LBA address.

Hardware:

Intel D875PBZ motherboard
Western Digital Raptor 36GB SATA drive
>How-To-Repeat:
      Happens randomly during normal use, even when the machine is idle. Usually takes anywhere from one to twenty minutes to happen, but I've had the system up for a few hours at most.
>Fix:
      Not sure. Looks like more ATA problems to me.
