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

Thanks Jerome!
Can you do a kick run on the modified patch ?
This one is also OK after ~60 iterations.
Jerome, could you
kexec works we need to disable any kind of GPU writeback

previous setup. This patch is done to fix the issue described in
the lkml thread :
