Dear all,

  when I tryied to mount an iso image over network (using samba) my computer
unexpectedly crashed.

 I issued this command : mdconfig -a -t vnode -f
/path/to/my/file/mounted/on-local-machine

 and since that kernel crashed, no ping response, nothing at all. I've been
connected to this machine via ssh.
I use 5.0 RELEASE with GENERIC kernel on P3/1 Ghz, 128 MB RAM.

It happens again when I issue same command and therefore I tryied to add
"dumpon=Yes" to my /etc/rc.conf, but nothing has been written to /var/crash.
So I enclose message from screen:

Fatal trap 12   : page fault while in kernel mode
faukt virtual address     = 0x0
fault code                    = supervisor read, page not present
instruction pointer        = 0x8:0xc1c50d4a
stack pointer               = 0x10:0xcd1b8718
frame pointer               = 0x10:0xcd1b8738
code segment             = base 0x0, limit 0xfffff, type 0x1b
                                 = DPL 0, pres 1, def31 1, gran 1
processor eflags          = interrupt enabled,  resume,IOPL = 0
current proccess         = 549 (mdconfig)
trap number                = 12
panic:fault page


Hope someone could explain me what happened.

Zbynek
