That message is NOT related to Hijack.

Things to do:

(1) Don't Panic. Nothing bad has happened yet, so don't try and make something bad happen!

(2) Reflash Hijack again, and see if that cures it.

(3) Revert back to the original empeg kernel, and see what that does (available from the Hijack site) -- there is no need to reinstall the empeg software.

Cheers
