             Bug #: 44549
           Summary: "Ring buffer test failed" on Radeon 5450
    Classification: Unclassified
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: ebischoff@nerim.net


linux kernel : 3.2.0
libdrm-radeon1 : 2.4.29
xserver-xorg-video-radeon : 6.14.99
motherboard : ASUS M2A-VM HDMI (*no* VIA chipset)
Graphics card : msi R5450 with 1 Gb onboard
RAM memory size : 4 Gb

Description : when booting, the message "Ring buffer test failed" appears in
dmesg log. A a consequence, the software rasterizer is chosen, and after X is
started, there is no 3D acceleration.

Workaround : when I add "mem=3G" to the kernel parameters, the message
disappears, and I get 3D acceleration. Of course, 1 Gb of RAM memory is lost
for the applications.

(log files will get attached to this bug report)

It's very similar to the problem described in
http://lkml.indiana.edu/hypermail/linux/kernel/1105.2/03496.html

Nevertheless, it's not exactly the same hardware conditions, and the radeon
driver patch that did solve that problem does not work for me.

Ouch, I just realized there was a "nomodeset" option left from an old test.
I'll see if that changes anything to the dmesg etc. Sorry.

Rebooted with correct kernel parameters and attached corresponding versions of
dmesg and cat /proc/cmdline. The other files do not change significantly. Sorry
for the mistake.
