Hmm, maybe you're seeing a different problem. The issue that I saw was fixed by commit 428c6e3630 in the git tree (this is identical to the patch by Dave you're referring to above). Does a "git-revert fe6f0bd03d697835e76dd18d232ba476c65b8282" solve your problem? > I'm not a kernel hacker by any means, so sorry if I understood > anything wrong; if I need to supply any additional information, I'll > be glad to. It would be great if you could git-bisect the issue. Basically you just need to run: git bisect start git bisect bad git bisect good ecff4fcc7bbaf060646d2160123f8dc02605a047 build new kernel (reboot) and then run either "git bisect good" or "git bisect bad", depending on whether you see the problem or not, and then repeat the last 3 items in the list. (please see also "man git-bisect") > Also, sorry for not continuing that thread; I have just subscribed so > I can't "reply" to it. (That's no problem. But it is always a good idea to CC the people that you're talking about and also the dri-devel list in this case) -- Markus _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
