Jiri, do you have i915 a module or build-in? Hi there Pavel, long time no see :) I have i915 built as a module. The thing is, that I can't really bisect this; the problem is, that I've started seeing this quite a long time ago, but only very sporadically (something like once in 40 resumes). But it was getting gradually worse and worse with newer kernels, and with current tree (both Linus' tree and drm-intel-testing), I am getting it 100% reproducibly on every resume. This makes bisection completely impossible though. -- Jiri Kosina _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
