Certainly not a valid one... :)
I just noticed that udevd didn't create /dev/cpu/microcode (it made
/dev/microcode) so microcode_ctl failed to run for 2.6.9-rc4.
I hope old microcode does not cause this kinds of things in the
kernel-land.
kernel: microcode: CPU0 updated from revision 0x4 to 0xa, date = 05051999
( Celeron Mendocino Original OEM 8) )
One minute before I was going to boot from 2.6.9-rc2-bk7-gcc2593 to 2.6.9-rc4,
I got more slab fun. 2.6.9-rc2-bk7 ran nicely for 18 days before this.

I had done "su -l luser" earlier, then pressed ^D in the luser's bash
and got the Oops.
