Wow, that's certainly a find! I can confirm that removing the dvd drive solves
the problem for me as well. Replacing the drive does not work, which leads me
to the conclusion which Cristian already wrote, that it's probably a failure in
the sis sata driver.
from "lspci -k" :
00:05.0 IDE interface: Silicon Integrated Systems [SiS] SATA Controller / IDE
mode (rev 03)
Subsystem: Silicon Integrated Systems [SiS] Device 1180
Kernel driver in use: sata_sis
Kernel modules: sata_sis
which would lead to drivers/ata/sata_sis.c in the source if I see this
correctly. Unfortunately that's where my knowledge ends.
