Since nobody has been able to reproduce this panic yet I did some more
testing today.

I wanted to find out if reading from the ext2fs was the sole cause for
the panic.

To cause the same kind of load I played music files from the ext2
partition in random mode on a different pc over network. No panic (~6
hrs up) yet.

Maybe there's a race if writing to dsp and reading from the ext2fs. 

dsp as sole cause is also unlikely because I've been listening for
longer times from cdrom/ufs2 without panics.
