Hi,
On my 6.0-STABLE #1: Mon Jan 23 00:45:10 EET 2006 while burning a DVD
image i got this:

systat -vmstat 1 shows between 400 and 800 interrupts while doing a
md5 over a 4GB file on the SATA disk and a few when no big reads are
done. On copying a 700 file from the PATA disk there are ~208
interrupts/second (while for the controller I'm copying from they are
approx. 1/2 - around 98-107).
I haven't seen any bad effects of this in the few hours I'm working
with this SATA disk. How worried should I be :) ?
