- What is printed when it enters DDB? (I guess this is on serial console;
please connect it before it crashes so you can see)
- Please include "ps" and "ps /o"

the prompt shows the cpu number in decimal, but the input to commands
(including "machine ddbcpu") is read in hex. therefore if you have cpu10
and higher, you either need to use hex, or specify that the number is
in decimal, i.e. "mach ddbcpu 0t10"

an outline of what you've got running on the system would be helpful too.
When you've collected this, please send it along with the information from your
first mail (so it's all self-contained and useful to someone without reference
to the earlier misc@ post) to [email protected].
