Ok, after looking at the changes for radeon I decided to try the HEAD of drm-next-3.19 (c81b99423bd9d3fc35ac8752ca5fb4c50eab063c). That was still = good. Armed with this much smaller bisection range, I came up with a result tha= t sounds at least believable: 3cd76f3901e73a4a61d78c4526dcbf6d87c9a928 is the first bad commit commit 3cd76f3901e73a4a61d78c4526dcbf6d87c9a928 Author: Christian K=C3=B6nig Date: Mon Oct 13 12:41:47 2014 +0200 drm/radeon: update the VM after setting BO address (v2) This way the necessary VM update is kicked off immediately if all BOs involved are in GPU accessible memory. v2: fix vm lock handling Signed-off-by: Christian K=C3=B6nig Signed-off-by: Alex Deucher :040000 040000 5bb1cc4497cc2e5b9af3a59170d7a8d5c99fd0a0 3df4996bc1a25f9275b833c778cdc33a30b28838 M drivers CCing Christian, maybe he has an idea, what's up. Let me know, if you need something else, to debug this or if I should fil= e this as a bug. > I noticed, however, that the following line is showing up with be762d18= 1e in dmesg: > [drm:ci_dpm_init [radeon]] *ERROR* Invalid PCC GPIO!=3D=3D power state = 0 =3D=3D This seems to be unrelated as it shows up with all the commits from the 3= =2E19 branch, I've tested for this bisection run, even those, that worked. (Mig= ht this be, however, related to ?)
