Are you sure it's a kernel-bug? (Please see below).

To my total astonishment: YES. After suid it also works as root!

-r-sr-xr-x  1 root  bin    261K Aug 19 18:18 /usr/local/bin/cdda2wav

Did that a couple of times, but the number of tracks seems to be
irrelevant.  After suid'ing cdda2wav it works with each and every CD
now, as root and as fpage.

I'm totally confused about what might be going on here :-(

Thanks for the hints, now I got a working cdda2wav on OpenBSD ;-)

Kind regards   Frederick
