That's strange.  It seems you got an AST trap but instead of being at
0x3000 it's at 0x3020 and caused the trap code to go "WTF?".  Can you do
a db> show event ?

Since that kernel loads at 0x100000, there is no code at 0x3000 NetBSD
will try to execute.  And if there was, I doubt it would know the magic
to call back into the trap code.

Did I say it was strange?
