I'm wondering if somehow the disk > controller is getting wedged? Indeed, this is what happens. I left my machine running "make world" overnight, with top running over the serial port, and came to find the machine had hung. The last message on the serial console was: ad0: READ command timeout tag=0 serv=0 - resetting ata2: resetting devices... And then it hung. Even processes that presumably do not access the disks once loaded (eg top) had hung hard. The box does still respond to pings, and prints "Power Failure Detected: Shutting down NOW." when the front power button is pressed. Could it be that it never recovers from the ata issue and then never returns to userland from the kernel? Extract from dmesg: atapci0: <CMD 646 ATA controller> port 0xc00020-0xc0002f,0xc00018-0xc0001b,0xc00010-0xc00017,0xc00008-0xc0000b,0xc00000-0xc00007 irq 32 at device 3.0 on pci2 ata2: at 0xc00000 on atapci0 ata3: at 0xc00010 on atapci0 ad0: 4103MB <ST34342A> [8894/15/63] at ata2-master WDMA2 Where do I go from here?
