The MCE reads: [Hardware Error]: CPU 0: Machine Check Exception: 4 Bank 4: ... [Hardware Error]: TSC 264f8ca046 and then continues about a NorthBridge Watchdog timeout. After that, there is kernel stack dump: See http://tech.unige.ch/mce.jpg or http://tech.unige.ch/mce.png for a screenshot. These always happen when I'm accessing disks attached to the TX4302, as far as I can tell. Motherboard is an Asus a8v, cpu is amd athlon64, stock ubuntu 11.04 kernel. I have no idea where to go from here though. I can provide any information required or test patches, please ask. Best, and thanks in advance, F. Beekhof
