Sorry for the misunderstanding; that's what I have always done, my
keyboard doesn't have an input.

I did some googling for the name of the function it's crashing in and
found this guy (also owner of a dell laptop):

http://lists.freebsd.org/pipermail/freebsd-current/2004-February/020942.html

Looks like the same crash.  He claims it's ata+acpi related; which I can
believe; and his symptoms persisted with our without acpi disabled (true
for me too.)

My dmesg has this funny error message in it, btw

ata1-slave: FAILURE - ATAPI_IDENTIFY no interrupt
ata1-master: FAILURE - ATAPI_RESET no interrupt

Is that safe to ignore?
