Hi,

I had that box under 2.1-stable running and did a 
umount -f /news  ; mount /news

the result was:

| Fatal trap 12: page fault while in kernel mode
| fault virtual address   = 0x80
| fault code              = supervisor read, page not present
| instruction pointer     = 0x8:0xf0172ee8
| code segment            = base 0x0, limit 0xfffff, type 0x1b
|                         = DPL 0, pres 1, def32 1, gran 1
| processor eflags        = interrupt enabled, resume, IOPL = 0
| current process         = 7171 (umount)
| interrupt mask          = 
| panic: page fault

I know that unmounting a filesystem which is not the best idea ... but
I think this should only lead to errors , not to panics ..
