I just upgraded from 2.6.18 distributed with Debian to 2.6.22.6.
I compiled ATA_PIIX directly in the kernel.
From time to time, the machine "freezes" for a couple of seconds, and
I'm getting the following logs (pasted below).
I didn't have anything like that with the old IDE.
The machine runs a 2 GB Transcend IDE flash disk.
Any ideas what it might be?
