6.0BETA4: panic: unrhdr has 9 allocations

[Rene Ladan]

Hi,

on

FreeBSD 6.0-BETA4 #10: Sun Sep  4 22:19:26 CEST 2005 /usr/obj/usr/src/sys/RENE 

I saw this panic after the following:

# mount_procfs procfs /proc
  (loads procfs.ko and pseudofs.ko)
<play with truss>
# umount /proc
# kldunload procfs

I'll leave the dump around for a while.
