Hello!

Just happened to write this kernel-module, which panics the machine.

It is, if you just set up your savecore-setup, you have to wait for a
panic to test, if it works. If this is a panic you would have liked to
savecore, and it didn't work, this can be annoying.

(At least that was my problem when setting up the savecore setup back
then) :)

Maybe something _like_ this (it depends on pci, which is not quite
useful) can be integrated to the save-core documentation in the
handbook, to make clear how to test your setup.

Comments?

Alex
