I guess Brad could try SLUB debugging, boot with slub_debug=P

Not much use I'm afraid.
This is all I get in the log

[ 3161.300147] BUG kmalloc-512: Freechain corrupt

The qemu process is then frozen, unkillable but reported in state "R"

13881 ? R 3:27 /usr/bin/qemu -S -M pc-0.13 -enable-kvm -m 1024 -smp
2,sockets=2,cores=1,threads=1 -nam

The machine then progressively dies until it's frozen solid with no
further error messages.

I stupidly forgot to do an alt-sysrq-t prior to doing an alt-sysrq-b,
but at least it responded to that.

On the bright side I can reproduce it at will.

Please try slub_debug=FZPU; that should point the finger (hopefully at
somebody else).

Well the first attempt locked the machine solid. No network, no console..

I saw "=========================================================================="

on the console.. nothing after that. Would not respond to sysrq-t or any other sysrq combination other than -b, which rebooted the box.

No output on netconsole at all, I had to walk to the other building to look at the monitor and reboot it.

The second attempt jammed netconsole again, but I managed to get this from an ssh session I already had established. The machine died a slow and horrible death, but remained interactive enough for me to reboot it with

echo b > /proc/sysrq-trigger

Nothing else worked.
