gdb sucks bigtime on alpha. The weirdness is just gdb throwing its
hands up in the air because it doesn't understand the trapframe and
can't grok anymore of the stack than that. gdb is useful for getting
stack traces from kernel panics on alpha only when a specific panic is
hit, not a trap.
So, you need to have ddb configured:
options DDB
options DDB_TRACE
and maybe:
options DDB_UNATTENDED
