You need to do "git cherry-pick 13cfc732160f7bc7e596128ce34cda361c556966" if the commit is not included. Before doing next git bisect, you need to `git reset --hard HEAD^` otherwise git will think the bisection is diverted and want to start the bisection again. But maybe we should just stick to

[Bug 1729010] Re: USB hub stops working after suspend(s?)

having some trouble with the bisect: -in order to be able to test this, the built kernel needs to include commit 13cfc732160f7bc7e596128ce34cda361c556966 which allows suspend on this machine to work -the bisect is picking commits like 6afafa7799cf6fa3c0efb6887704506d21965ad6 that don't descend

If you can build/test it locally, it should be quite quick: $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux $ git bisect start $ git bisect good v4.12 $ git bisect bad v4.13-rc3 $ make localmodconfig $ make -j`nproc` deb-pkg

Great. We should still backport fixes to Artful though. It might be time consuming to install and test multiple kernels. Are you up to the task? ;) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

Hmm, there are several subsystems might affect xHC, so we need to bisect between v4.12 and v4.13-rc3. Before we do that, can you try latest (v4.16-rc2) mainline kernel again? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14
