maybe set ddb.panic back to the default (1) and try to collect more from
ddb? at least ps /o and ps, and a trace from each cpu (use mach ddbcpu
followed by the cpu number to switch - the default radix in ddb is hex,
so as your numbers go above cpu9 use "mach ddbcpu 0t10" etc).
"show mbuf" and "show all pools" are often useful too.

you're not going to be gaining anything from so many cores on OpenBSD
yet, and extra cores aren't without costs to the os. is there an easy
way to disable one of the two CPU chips ("package"s)?
