Comment 141 for bug 285392

As of now, I have tried these combinations of kernel boot parameters:
"acpi=off": bug occurs after 40 hours of operation
"acpi=off noapic": bug occurs within the first 10 minutes of operation
"pci=nomsi": bug occurs within the first 10 minutes of operation

Strange enough, this only happens on the second HDD attached to the controller, the first runs flawlessly.

My mainboard is a Supermicro H8DI3+/i+/L+(-F), with a SB700/800 SATA controller:
00:11.0 SATA controller: ATI Technologies Inc SB700/SB800 SATA Controller [AHCI mode] (prog-if 01 [AHCI 1.0])
 Subsystem: ATI Technologies Inc SB700/SB800 SATA Controller [AHCI mode]
 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 10
 I/O ports at c000 [size=8]
 I/O ports at b000 [size=4]
 I/O ports at a000 [size=8]
 I/O ports at 9000 [size=4]
 I/O ports at 8000 [size=16]
 Memory at fdcff800 (32-bit, non-prefetchable) [size=1K]
 Capabilities: [60] Power Management version 2
 Capabilities: [70] SATA HBA <?>
 Kernel driver in use: ahci

So this seems to be a kernel issue. Is this already being pushed upstream?
