The raid trouble in mm also exists in 2.5.70-bk7

I get several stack traces and a final oops
in interrupt when trying to boot. Thanks to
matroxfb and the 8x8 font, I now have a nice long trace.

This is not the first in the row, but not the last one either.
My reports about mm always were the last one.

After this came several messages about unregistering md1
(the raid-0 array) before the final oops.

I use raid-1, raid-0, preempt, smp & devfs, all fs'es
are ext2. I don't use modules.

Here is the trace:
raid0_run
raid0_run
printk
blk_queue_make_request
do_md_run

autorun_arrays
printk
md_fail_request
autorun_devices

Slab error in cache_free_debugcheck
cache `size-32' double free, or memory after object
overwritten
