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
(2.9.5.0.31-2.arm1)?
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
2.4...
Thanks,
