    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.
