:Hm:
:"/home/var.vkernel/memimg.000000" is not a core dump: File format not
:recognized" guess not? (tried it with gdb not kgdb)
Heh. No but you CAN gdb the live vkernel (assuming it dropped into
db> it is still running).
In anycase, don't bother going that far. There's definitely a bug
here. The vnode is supposed to have a VM object associated with it
and clearly there must be a path where that vnode can be instantiated
without one.
Can you by any chance reproduce the bug to test that this patch
fixes the problem?
