This is very bizarre. The errors being returned from acd0 are that an
ATAPI/ATA command (READ_BIG, whatever the code for that is) did not
receive a response from the controller or device within 5 seconds
(assuming the ata(4) timeout values here; it could be something larger
for ATAPI, I don't know). Maybe some a BIOS bug...
Can you show us output from the following two commands?
Soren, do you know how/if the HPET time counter could cause this oddity?
All of my systems use ACPI-fast, so I can't test this.
