On this partition my music collection is stored. Normally I run cplay
(CLI music player) in shuffle mode. So there is a low but constant load
on the drive. I'm not sure about this, but at least sometimes the panics
seems to happen immediately after a new file is opened.

The only special thing I can think about is that I created it with the
largefile4 (one inode per 4 megabytes) option in knoppix. As I mentioned
above it is mounted read-only.

Thanks. So I can (hopefully) run a recent CURRENT somewhat stable at
least until this is resolved.
