Stephen Thirlwall: >"One question: should I be using the latest mainline kernel, or the latest drm-intel-nightly for the Kernel.org bug report?"
Given you would report this to the linux-gfx mailing list, you would want to emphasize you tested both drm-intel-nightly and latest mainline kernel. However, to speak to Peter Frühberger's point, if a confirmed regression occurred in the mainline kernel series, and persists all the way up to drm-intel-nightly, it is highly probable upstream will ask for a bisection, and the report may stall on that unfortunately. Hence, the next step is to fully commit bisect the mainline kernel (not Ubuntu repository kernel) from kernel 3.19.8-ckt4 to 3.19.8-ckt5 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
