Thanks a lot Alex / Gerd and Thomas, very informative stuff! I'm glad there are projects to collect/save the data and reuse after a kdump, this is very useful. I'll continue my study on the atombios thing of AMD and QXL, maybe at least we can make it work in qemu, that'd be great (like a small initdriver to reprogram de paravirtual device on kexec boot).
Why not just reload the driver after kexec? Alex
