panic: tmpfs_alloc_vp: type 0xffffff000143d380 0

Hi,

Got the following panic after I built some ports with
WRKDIRPREFIX=/tmp/work where /tmp is tmpfs.

FreeBSD one 8.0-CURRENT FreeBSD 8.0-CURRENT #0 r184639M: Tue Nov  4
18:39:44 CET 2008     root_at_one:/usr/obj/usr/src/sys/IBMT61  amd64

panic: tmpfs_alloc_vp: type 0xffffff000143d380 0

Unread portion of the kernel message buffer:
panic: tmpfs_alloc_vp: type 0xffffff000143d380 0
cpuid = 0
