Unfortunately, the system(running the kernel built from the source
with the patch in the previous message on top of 94603b1be) panicked
after 10 and a half hour later.  So I guess I've chosen a wrong
`good' kernel for bisecting.  /boot/kernel.old/kernel contains
DragonFly v2.9.1.231.g0b38f which is a non-kernel local patch to b911043fd,
but the first entry in `git bisect log` is fc55f5f28.

The problem is I don't have the Linux binaries necessary to build it,
and the URL in the message is 404.
