xmon should do something similar.  When a machine croaks on one CPU, its
often/usually interesting to know what the other CPU's are doing.   That is,
typically all the cpu's in the complex are involved in some sort lock
contention, and its pointless to let the other cpus 'keep going' while
one is stopped.
