tmpfs panic: wrong vnode type 0xffffff008547ab10

Hi,

I tried to run my tinderbox with the build directory on tmpfs but the
system panics with wrong vnode type 0xffffff008547ab10.

This panic is reproducible when mounting the build directory with tmpfs
and trying to build a port like gcc or openoffice with tinderbox.

System was updated today:
FreeBSD tindi.chruetertee.ch 8.0-BETA1 FreeBSD 8.0-BETA1 #1: Fri Jul 10
09:35:41 CEST 2009
root_at_tindi.chruetertee.ch:/usr/obj/usr/src/sys/GENERIC  amd64

I know tmpfs is still experimental but maybe someone would like to have
a look at this panic.

crashinfo is available here: http://tmp.chruetertee.ch/core.txt.1

Thanks,
Beat
