I didn't apply the kdb patch because it had a problem patching main.c
from the stock debian kernel (which is very close to kernel.org). 

patching file init/main.c
Hunk #2 FAILED at 255.
Hunk #3 succeeded at 448 (offset 18 lines).
1 out of 3 hunks FAILED -- saving rejects to file init/main.c.rej

Maybe I should start from a CVS xfs full kernel tree, then apply
the preempt patch on it so that I'd get kdb.
