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)

--- Comment #1 from Eric Bischoff ebischoff@nerim.net 2012-01-07 03:45:18 PST --- 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.

--- Comment #8 from Eric Bischoff ebischoff@nerim.net 2012-01-07 04:45:33 PST --- 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.
