Thanks for the clue-by-four :-) I can now analyze the dump.

I was mislead because I got the same error using what I thought was a
standard "-g" kernel. It turns out a coworker put the kernel-debuginfo
vmlinux in our /linux/debug_kernels filesystem. That directory should only
contain kernels we've built from source with the -g switch; nothing else.
Grrrr.
