My hunch is that this is somehow related to the onboard Intel | ICH5 controller and SATA HD, because during reboot after a lockup, | the machine often complain of a DMA timeout that hangs the box | while reading from the SATA drive. FYI, if the drive has a media error or does a spin down/spin up sequence things will hang since the ata driver currently doesn't deal with the SATA PHY registers. After a while of ignoring various issues flagged in these bits your system will lock up solid on a inb/outb to the controller. Doug A.
