I was finally able to do a crash dump--using an otherwise unused disk
(da0s1b) as dump device helped. Note that disk numbering has shifted
by one due to the addition of that extra disk, i.e. the vinum config
is now

Note also that the other disks are not exclusively dedicated to
vinum (dunno if this is relevant).

Some comments on the stack traces below:
- The crash always happens at exactly the same position: the "lp" pointer
(line 198 in dscheck()) is faulty. Sometimes it's 0xffffffff, sometimes
it's some random value; but it's _always_ the "lp" pointer.
- Given my limited understanding of the disk subsystem internals,
the hosed data structures seem to represent stuff (struct
disklabel*, struct diskslice* ..) that doesn't normally change
while the associated disks are in active use.
Is it possible that some routines (e.g. dsinit(), dsopen()) called by
one of the vinum processes (PID 352) are simply not designed to be
called after the initialization phase of the kernel is over?
See also the comment for dsopen():
| 628 /*
| 629 * This should only be called when the unit is inactive and the st=
rategy
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| 630 * routine should not allow it to become active unless we call it.=
Our
| 631 * strategy routine must be special to allow activity.
| 632 */
