Yes, same experience here. But I unfortunately did not have a serial
console handy. Tanimura's commits on March 14th were supposed to help the
situation, but they appearently haven't...:-(

I am still trying to figure out how to get more. I am not good with ddb,
and since the machine will not dump, gdb is not usable locally. (And again,
no serial connection handy:-( 'show witness' and 'show mutex' come to mind
as two more things I will try in ddb.

Yes, I think we are looking at the same thing.
