I tried this patch, and while it does get rid of that particular error
message, I have a feeling it's (ACPI/the patch/or something) causing my
system to overheat, making it power down after a while. Funny thing is
that this only seems to happen while I'm in a dockingstation (ThinkPad
T21 + Dock). And with ACPI disabled, the machine refuses totally to
boot, it hangs at 'Mounting root from ...'. If I undock the machine, I
can boot with and without ACPI, with the latter option being the only
usable (stable) mode.
