The > backtrace was always somewhat different. 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.
