Hi Jonathan,
can you do an other simple test ?

Run colinux on vista.
Then digit :

# n1=$(cat /proc/interrupts | grep "0:" | awk '{ print $2 }')

wait <n> seconds on you hand-clock (Don't use sleep command ! we are
studying the PC timer taht seems broken! ). Then exec a new command

# n2=$(cat /proc/interrupts | grep "0:" | awk '{ print $2 }')

Now digit
# echo $(expr $n2 - $n1)

Get the value and divide it by <n>.

You should have a value very closed to 100. Is it ?

Run an other linux distribution that works
Use the same procedure written above.

You should have 100 or 1000 (or 250) .... Depends on the HZ defined
into kernel ....
What is the value you see ?




I've got a Athlon64 x2 with same bios problem (which it had not before last bios update). I can confirm Ubuntu 7.10 did not pass booting without acpi=off parameter. 
Should this help debugging I can send more data|run some test.
