Currently, yes. But above mention "and other days before that". So presumably
you have knowledge of other crashes, yes? That we haven't gotten data on, yes?
So far, the crashes I've encountered are:
1. Hangs. Cannot break into DDB.
Observed on: XP1000, Rawhide, PC164
Activities: Varying from nothing to buildworld
Frequency: Infrequent (every few days maybe)
I've been remote for the Rawhide one, otherwise I would have gone over and
gotten the PC at least.
2. Hangs when rebooting
Rawhide only. This is clearly an SMP issue. This probably is because we don't
stop the other CPUs when rebooting.
3. Random blockable sleep lock panics
June 4, Rawhide:

We're scratching our heads over this one.
Others- less complete info..
By and large, the single processor systems now seem to be functional for me.
