Nearly every time I did an OIR of a VIP2 board in recent 12.0S IOS releases
(12.0(26)S), I've seen similar messages.

My interpretation was "it's very easy for the bus to get stuck, and there
is no way to recover from this besides a hard reset".

"show diag" in this situation shows the controllers as "wedged", and
nothing I did would revive the boards.

The interesting thing is that earlier 12.0S and 11.1CC releases are not
*that* picky - my success ratio was much better, and usually only the
VIP in question crashed, not another, completely unrelated board - seems
they changed the bus protocol / bus timing quite significantly...
