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. > It should be easy to turn off the selwakeuppri() chnages by editing a > line or two of selwakeuppri(). From sys_generic.c: Thanks. So I can (hopefully) run a recent CURRENT somewhat stable at least until this is resolved.
