This is the result of the bisect. Unfortunately I had to skip some kernels because they wouldn't compile.

    drm/radeon: enable pci bus mastering after card is initialised (v2)

    This closes a race seen with kexec where we enable PCI bus mastering
    but the card has been reinitialised fully yet.

    This was previously fixed by a patch from Jerome, but this should
    close the race completely.

    v2: add SI support as suggested by Alex.
