Only slightly patched. But they are definitely kernels I have built
myself. It might just be a logistics problem where if I want to use
crash I need to upgrade it when I upgrade my kernels.

I got frustrated a while ago trying to get something out of crash
(and I'm afraid it shows), and I have just gone to extracting the
dmesg. Which gives me all of the information I generally have time
to process.
