[Bug 1577898] Re: thunderbolt hotplug is broken

[FireBurn]

A patch https://patchwork.kernel.org/patch/10212201/ is going to fix
this issue properly, it should be backported to older kernels too, so
hopefully going forward your USB-C connectors will work correctly, it
also fixes NVMe drives disappearing after suspend too

[Kamal Mostafa]

Thanks for validating Xenial, Mario.

We appreciate getting validation for as many versions as possible, but
no, we're not really going to drop this fix from the earlier versions.

[Bug 1577898] Re: thunderbolt hotplug is broken

[Mario Limonciello]

Hi,

I verified the kernel in xenial works properly for hotplugging the TB15.

Linux test-Precision-5510 4.4.0-23-generic #41-Ubuntu SMP Mon May 16
23:04:25 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Does there really need to be a validation done on every other OS too or
this gets dropped from earlier -proposed kernels?

Nothing else required from you.  It's the Ubuntu kernel team SRU process
from here on out.  Joseph might be able to comment better on the expected
timing this will land in a new kernel version.

I can confirm that I can hotplug my Dell USB-C to ethernet adapter, as well as 
my Nexus6p with a USB-C to USB-C cord as well.

So the patch is working for me as well. What does the process involve
from here? (first time dealing with a bug here).

Re: [Bug 1577898] Re: thunderbolt hotplug is broken

[Mario Limonciello]

You're still booted into the wrong one. His kernel would show a ~lp# in
the uname string. The one your are booted into is probably the one from the
archive that overwrote his on an apt update.

Install his again, don't do apt updates and try to boot into it.

Mario,
I found the issue. I am running 4.6.0-040600rc4-generic from testing in my bug

GRUB on the reboot and booted into 4.4.0-21 which matches his kernel.

I get this now for uname -a:
Linux yeti 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 
x86_64 x86_64 GNU/Linux

But hotplug does not work still. Again, I still could be screwing up
changing up the kernels, so take with a large grain of salt.

Kyle,
Can you confirm from 'uname -a' what output you have?

That will confirm if you are booted into jsalisbury's kernel.

I have duplicate bug #1571859 and tried the kernel above from jsalisbury and it 
did not work for me. However there is a chance that I may just suck at dealing 
with kernels though. 
(I installed all the packages except for the Cloud Tools.)

Hi Joseph,

Yes, thank you.  I just tested with a Dell USB Type-C ethernet adapter (PN#
96NP5).  In the existing latest Xenial kernel hotplug did not work.  Device
wasn't present in lsusb.
After installing that kernel i'm able to hotplug and device is present in
lsusb.

Thanks,

I built a Xenial text kernel with the patch.  The test kernel can be
downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1577898/

Can you test this kernel and see if it resolves this bug?

[Joseph Salisbury]

We generally like patches to land in mainline before applying them to
the Ubuntu kernel as a SAUCE patch.  This can prevent issues if the
patch changes before it actually gets accepted into mainline.

However, this patch looks fairly small, so I'll build a test kernel with
it and post it shortly.

Why do you have to wait for it to be in mainline to cherry pick?  It's
already in rafael's linux-pm acpica-fixes branch with a CC to stable all
applicable.

It doesn't look like the patch landed in mainline as of yet.  As soon as
it does, we can cherry-pick it into the Ubuntu kernels.

There aren't logs for this.  it's  a request to backport a patch.
