I'm working on a version of the patch that will produce a SHA1 checksum
of the image pages on save/load. This will then eliminate problems
related to pages not being saved/loaded correctly by threads etc.
I'll send you that when I test it. If that still panics your kernel
after the checksums have been verified, then we have another problem
somewhere.
