Perhaps the PCI SCSI controllers are hogging the PCI bus and not } giving the PCI IDE disk controller enough bandwidth? The system is } crashing only during expires. INN was built with ACT_STYLE READ. Is this a Saturn based motherboard ? If yes: There might have still been first generation Saturn chip sets been used, which had a few bugs if used with PCI write buffers and burst mode. The Saturn II (== rev. 4) i sknown to work reliably ... I've had other reports of stability problems before, and the system worked flawless after switching off PCI burst mode in the PCI BIOS setup. The failures occur only under high load, as seems to be the case for you, too. Send VERBOSE boot messages if you are not siure about the chip set in your system, and I'll try to identify it and let you know whether it is known buggy ...
