This is a duplicate of: https://bugzilla.kernel.org/show_bug.cgi?id=43207 Created attachment 62070 [details] [review] Fix backend map This patch should fix your issue. *** Bug 50891 has been marked as a duplicate of this bug. *** I applied the patch, but it did not solve the issue. I am not 100% sure I applied correctly (it's the first time I did this...), but I followed the instructions from http://fedoraproject.org/wiki/Building_a_custom_kernel so I think I'm quite confident. Reminder : my bug was #50891 I forgot to mention that I received the following errors on the console : [ 35.086959] radeon 0000:01:00.0: GPU lockup CP stall for more than 10020msec [ 35.086968] GPU lockup (waiting for 0x00000003 last fence id 0x00000001) [ 35.088218] radeon 0000:01:00.0: GPU softreset [ 35.088225] radeon 0000:01:00.0: GRBM_STATUS=0xB1403828 [ 35.088232] radeon 0000:01:00.0: GRBM_STATUS_SE0=0x28000007 [ 35.088238] radeon 0000:01:00.0: GRBM_STATUS_SE1=0x00000007 [ 35.088245] radeon 0000:01:00.0: SRBM_STATUS=0x200000C0 [ 35.088262] radeon 0000:01:00.0: GRBM_SOFT_RESET=0x00007F6B [ 35.088370] radeon 0000:01:00.0: GRBM_STATUS=0x00003828 [ 35.088376] radeon 0000:01:00.0: GRBM_STATUS_SE0=0x00000007 [ 35.088382] radeon 0000:01:00.0: GRBM_STATUS_SE1=0x00000007 [ 35.088388] radeon 0000:01:00.0: SRBM_STATUS=0x200000C0 [ 35.089395] radeon 0000:01:00.0: GPU reset succeed [ 35.170461] [drm] PCIE GART of 512M enabled (table at 0x0000000000040000).

I'll be very happy to help, if there is anything I can do to help fixing this bug! (some more logs, tests, patches...) Goulou. A patch referencing this bug report has been merged in Linux v3.5-rc1: commit 95c4b23ec4e2fa5604df229ddf134e31d7b3b378 Author: Jerome Glisse <jglisse@redhat.com> Date: Thu May 31 19:00:24 2012 -0400 drm/radeon: fix HD6790, HD6570 backend programming The patch alone did not seem to work, but I'm now running kernel 3.5.0-rc4 (rpm from Fedora 18, installed on F17), and I can confirm that, for the first time ever, the radeon driver works for me!! As of now, it seems pretty slow thought, but I will check again later : the reboot harmed my raid and it is re-syncing now... Anyway, at least I'm running a really free driver :-) -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
