            Bug ID: 89808
           Summary: [Radeon 9600 r300] Xorg fails with radeonfb and KMS
           Product: DRI
           Version: unspecified
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: chris.bainbridge at gmail.com

A recent 3.19.0 kernel with radeonfb and KMS results in hang and corrupt video
display after Xorg loads. It seems that radeonfb and KMS together will not work
(?), but I could not find any information about this apart from this
discussion:

"I believe we will enforce to either have radeon KMS or radeonfb the latter
being depreciated. Note we need to wait few years (5 maybe more) before we can
do rm radeonfb at least this is my understanding of kernel rules."

So KMS and radeonfb should be mutually exclusive build options, or perhaps
radeonfb should be finally removed as suggested (the suggestion to remove it in
a few years was made in 2009)?
