[Kai-Heng Feng]

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 Bionic's kernel - seems like there are
lots steps in bisection to go through.

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

[Joe Barnett]

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 from the suspend fix commit
-I've tried starting the bisect from 13cfc732160f7bc7e596128ce34cda361c556966 
as 'good', but am still getting commits picked by the bisect that don't include 
that change.

any pointers on bisecting bewteen
13cfc732160f7bc7e596128ce34cda361c556966 and v4.13-rc3 ?

(I have confirmed that building at

[Kai-Heng Feng]

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
Install the newly built kernel.
If the issue still happens,
$ git bisect bad
Otherwise,
$ git bisect good
Repeat to "make -j`nproc` deb-pkg" until you find the commit that causes the 
regression.

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? ;)

Thanks for your testing!

Can you also try latest Ubuntu Bionic? We need to backport fixes if
Bionic also has this problem.

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?

USB mass storage devices appear to have the same problem as the hub i
was using, while usb keyboards continue to work ok even when the hub &

reproduced the issue on v4.13rc3.  both rc1 and rc2 appear to be very
unstable resulting in full graphical lockups.  believe I reproduced the
issue on rc2 as well, but hard to tell with the general instability.

IIRC, Artful used v4.11 and v4.12 before GA. Do these two versions have
the same issue?

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

[Joe Barnett]

It did not occur on previous ubuntu releases, and didn't occur during
the artful dev cycle either.  It seems to be on a suspend-by-suspend
basis: after reproducing, another suspend cycle seems to "fix" it at
least some of the time.

[Kai-Heng Feng]

You were using the system from 15.10, did this issue occur in previous
kernel versions?

its not instantly reproducible so it'll take a while to ensure it's
really gone, but i'll run with my last installed kernel (4.13.0-12) for
a while and see, and then also try the latest mainline 4.14 and report
back

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

[Joseph Salisbury]

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 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.
