Heavy disk read load on any other drive (tar c /path | cat > /dev/null) Since it shows up under heavy load that includes unrelated devices, I think ruling out hardware problems is important. Some suggestions: - Use mcelog to see if you're getting any machine check exceptions that would indicate hardware error: http://freshmeat.net/projects/mcelog/ - Use the edac module to turn on pci parity and memory error checks: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/drivers/edac/edac.txt - Run memtest86+ for several loops to make sure your RAM is ok - Try moving the SiI card to a different slot - Try running the SATA drives from a separate power supply - Move disks and cables around to see whether the problem follows the disks, the cables, or the controllers - Try enabling the "spread spectrum" clock option in your BIOS to reduce EMI -jim - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
