Could you retest this against the latest drm-tip? I pushed something that I think might fix this On Thu, 2021-03-25 at 21:53 +0800, Oliver Sang wrote: > Hi, Lyude, > > On Tue, Mar 23, 2021 at 01:27:29PM -0400, Lyude Paul wrote: > > BTW Oliver - I'm still happy to look at this issue, I just need

BTW Oliver - I'm still happy to look at this issue, I just need the extra logs I mentioned below in order to figure out what's going on here On Thu, 2021-03-18 at 13:16 -0400, Lyude Paul wrote: > Well this is surprising, because I had been pretty sure we had asked someone > at > Intel to test

linux-5.12-rc3 has fixed at least one long-standing issue with BDW-samus (Google Chromebook Pixel 2015 I think): https://intel-gfx-ci.01.org/tree/linus/combined-alt.html https://intel-gfx-ci.01.org/tree/linus/fi-bdw-samus.html I can test anything on this type of host, just explain me the
