This may be fixed in Debian's 2.6.32 now as we have applied several
fixes originally made in later versions.

If you don't use the parallel port, you may be able to work around this

I see several reports of this against other distributions, but no sign
of it being tracked down or fixed.  Therefore, please report it upstream
at <https://bugzilla.kernel.org> under product 'ACPI', component
