It looks like we run out of hardware contexts, invalidate them all and flush
   caches. Then we hit a window fill trap and something else in the wrong order
   and RED state.


FYI: my ultra1 running 32 bit kernel 1.6D the other day hit a SIR reset in
the window fill trap.... that kernel ran for 105 days, got kinda unhappy so
i rebooted and a couple of days later the SIR reset.
