Folks,
  Got a sparc10 with an SM61 here...running -current as of a day or
two ago.  Under periods of heavy load, it invariably panics at
"pv_unlink".  Not "pv_unlink0" as was discussed at great length over
the past few weeks, but a panic call further down in the middle of
pv_unlink4m().  Being relatively unfamiliar with the internals of
those routines in pmap.c, I gave up on my own debugging efforts after
about ten minutes.

  Does anyone have any advice as to how I should proceed with this
issue to try to help get this fixed?


                        Thanks,
                        -Dave McGuire
