If I had to guess it looks like 0 is getting written back to some random page by the GPU maybe, it could be that the GPU is in some half setup state at boot or on a reboot does it happen from a cold boot or just warm boot or kexec?
Only happened with kexec thus far. Cold boot seems to be fine.

Can you add radeon.no_wb=1 to your kexec kernel paramater an see if you can reproduce.
No, I cannot reproduce the issue with radeon.no_wb=1. (I write this after 700 successful kexec iterations...)
Ok so it's GPU writeback will do a patch on monday.
