Yep, I had a similar problem on my old Gateway Solo 2150 that was
rectified by a bios upgrade. Under windows it would happen rarely, but
it did occur, under Linux it was unusable. A bios upgrade for the
keyboard controller fixed both :p)
In this case, it is caused by polling ACPI status. Only under 2.5
though, 2.4 works perfectly.
