E on Netwinder causes kernel oops (2.3.99-rmk2)

Okay, so I've got my new kernel up and running, and X starts and gdm
logs me in, but Enligtenment is doing something such that the machine
hangs.  The machine still responds to pings, and I still hear drive
clicks, but I can't ssh in (the connection is refused), and first mouse
clicks do nothing, then the keyboard becomes inactive, then the mouse
doesn't move, then ssh fails with no error message.

If I switch out to the console (ctrl-alt-F1) early enough while E is
starting, I see:

Bad swap offset entry ef9f0000

over and over.  A kernel oops goes by too fast to see.  The keyboard is
still working, so I can type, and stop /etc/init.d/gdm to shut down X.
I get a last kernel oops before the prompt, which is attached.

Any ideas?  Where can I send such a bug report?

This is with 2.3.99-rmk2 and the latest potato.  (Same happened with
-rmk1, which is why I built rmk2.)

Might it help to rebuild the kernel with the new binutils

Uh oh, new error, now it's spewing:

kmem_alloc: Bad slab magic (corrupt) (name=buffer_head)

The keyboard is responding, but it's not doing anything with my
commands, like reboot does nothing. :-(

Seems we have some serious memory management issues to work out before
