Well, something in the initscripts could be telling the kernel to do
something bad.  Maybe to do with the rootfs, or swap.  Then it might be
acceptable for the kernel to panic and that wouldn't be a kernel bug.

Probably some initscript is at fault here, but since I don't know which
one yet, I filed against sysvinit until we know where to reassign it.

I'm not sure that fsck itself causes this.  Because if I boot a shell
instead of /sbin/init, and run initscripts manually (including fsck), it
doesn't panic.

I think when sysvinit runs initscripts in parallel, it does some
buffering of console output, so that makes it hard to know what was
running at the time of the panic.  I think fsck must have already
finished running when the panic happens (or else we wouldn't see it
mentioned?).
