PREEMPTION still unusable with 6.0-RC1

[Stefan Ehmann]

I recently upgraded my 5.4-RELEASE machine to 6.0-RC1. Runs fine so far
if I disable PREEMPTION.

With PREEMPTION enabled, I still get the same issues as described here:
http://lists.freebsd.org/pipermail/freebsd-current/2004-September/037949.html

kernel config:
http://stud4.tuwien.ac.at/~e0125637/fbsd/kernconf-6.0-RC1

/var/log/messages output:
http://stud4.tuwien.ac.at/~e0125637/fbsd/messages-6.0-RC1

Any one else still experiencing these problems or has any idea what
causes this?

BTW, are 6.0 discussions supposed to go to stable@ once 6.0 is released?

Thanks,
Stefan
