First of all you don't need to always specify the commit, git knows that by
itself. E.g. "git bisect good" without the commit hash should be =
sufficient.

That's unfortunate but happens sometimes. Since
c5fd936e992dd2829167d2adc63e151675ca6898 is bad the problem must be somewhe=
re
between v4.1 and c5fd936e992dd2829167d2adc63e151675ca6898.

Since it is a radeon driver problem I suggest you limit bisect to only test=
 the
changes made to radeon.

Please try the command "git bisect start
c5fd936e992dd2829167d2adc63e151675ca6898 v4.1 drivers/gpu/drm/radeon/".

If that still doesn't work try "git bisect skip" if you have a co=
mmit that
won't work at all.

If that also doesn't work just go on with "git bisect good/bad" a=
nd try to
figure out when the issue with the ramdisk started.
