First Fedora Kernel with broken video resume/thaw aka FFKWBVRT i.e. kernel-3.16.0-0.rc0.git10.1.fc21 comes with 'patch-3.15-git10.xz' which closely resembles "git/commit/drivers/gpu/drm/nouveau?id=7a014a". Simple as that. Why are you asking me that bisect formality, man is it not enough that I tested two dozen kernels. poma

Dear Poma, Don't get anyone wrong, your input is greatly valued. The reason why "we" (nouveau developers) generally ask for a git bisection is because we don't know or track specific distributions. Although your search has narrowed the problem down (thanks for that!), we don't know how big the difference is between kernel-3.16.0-0.rc0.git9.1.fc21 and kernel-3.16.0-0.rc0.git10.1.fc21. Is the difference literally just that one patch? Or were there more patches to nouveau or drm that might have been the culprit? So far I haven't succeeded in finding the exact differences between the two kernels. Git bisect on the upstream kernel on the other hand will always point at the precise patch that broke the kernel, narrowing down the search space of the bug for developers thus reducing the time it takes to fix your issue. Unless developers can reproduce your issue, Unfortunately the user is the person who has to do the bisecting. So in short: narrowing down the search space often saves a lot of time of the developer, reducing the time it takes to fix your issue! Thus, if you can find the time to perform a git bisect (with the right good/bad markers it really should not take that many kernels to build), or if you can validate that the patch you mention *really* is the only difference between the two kernels, it'd be greatly appreciated. Thanks!

Knowing the exact commit that breaks things is a fairly useful debug tactic, and drastically increases the chances that a problem gets fixed. Not sure why you're referring to it as a formality. git bisect start v3.16-rc1 v3.15 -- drivers/gpu/drm/nouveau (Pro tip: use a config tailored to your machine rather than a distro config if you want to spend 5 min/compile instead of 1 hour/compile) Or you can wait and hope that someone else will have the same problem and works out the commit that causes it. Or you can see if it has already been fixed in the latest kernels. Or try the experimental repo at http://cgit.freedesktop.org/~darktama/nouveau/ (a bit of a pain to build, unfortunately, you need some unknown kernel version to build against, usually ~latest works).
