[Dell Precision M3800] USB is dead after resume from sleep

[Konstantin]

After resuming from sleep (suspend to ram), all external usb ports are dead.

The laptop's built in keyboard and synaptic touch pad (I think it is vonnected via internal usb, but not 100% sure) still work.

Only a complete power down and reboot seem to bring back the devices.

The problem does not happen with the previous kernel 3.13.0-36.

Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 stable 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'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Konstantin (list-kseiler)]

The issue is still there with the upstream kernel 3.13.11-03131109-generic.

See attached for the syslog of boot-sleep-resume-shutdown. Usb was dead after resume.

[Konstantin (list-kseiler)]

I did the Bios update. It didn't change anything and the problem still exists.

The output of the command you requested is:
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

========

After resuming from sleep, the USB ports are dead. (i.e. extenal mouse and Keyboard don't work and the red light of the optical mouse is off, etc.). The problem happens with 3.13.0-37, but not with 3.13.0-36.

Thank you for your support.

[Joseph Salisbury (jsalisbury)]

Can you also test the latest mainline kernel? If the bug is still there, we can perform a kernel bisect to identify the commit that introduced this regression:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc1-utopic/

[Konstantin (list-kseiler)]

Joseph, I just tested the kernel you asked me to and the problem still exists with
Linux mana 3.18.0-031800rc1-generic #201410192135 SMP Mon Oct 20 01:37:04 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

I made an interesting observation though:
When I ran 3.13.0-36 and performed a reboot into 3.18-rc1 without power down everything worked fine.
(boot 3.13.0-36, reboot into 3.18-rc1, suspend, resume => usb is alive)

However, if I do a complete shutdown and then boot into 3.18-rc1, usb us dead after resume.
(power on, boot into 3.18-rc1, suspend, resume => usb is dead)

I've tried each way to boot twice.

[penalvch (penalvch)]

Konstantin, could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc2-utopic/ and advise to the results?

[Konstantin (list-kseiler)]

Bad news.

 v3.18-rc2-utopic screws things up completely and the system doesn't boot.

The symptoms are as follows:
- the initramdisk doesn't show the password prompt to unlock the full disk encryption.
- the external usb keyboard doesn't work (i.e. I can't use ESC to hide the splash screen on the external keyboard but I can use ESC on the internal keyboard. However it is not a complete USB outage since both, the keyboard and mouse are showing lights. The external keyboard does work during grub though)
- after hiding the splash screen it tells me something about not finding any volume groups (not really surprising if it skips the disc encryption...)

I tried to run dpkg -i on the three kernel packages again to re-generate the initramdisk and look for errors. I didn't see any relevant messages and it still failed to boot. The kernel packages I used were

linux-headers-3.18.0-031800rc2_3.18.0-031800rc2.201410262035_all.deb
linux-headers-3.18.0-031800rc2-generic_3.18.0-031800rc2.201410262035_amd64.deb
linux-image-3.18.0-031800rc2-generic_3.18.0-031800rc2.201410262035_amd64.deb

I dare say, there is another issue at work here than the one we were dealing with so far.

[Konstantin (list-kseiler)]

I thought I might sum up the Kernels that were tested so far and their results:

3.13.0-36: everything is ok
3.13.0-37: usb dead after resume
3.13.11.9-trusty: usb dead after resume
3.18-rc1-utopic: usb dead after resume
3.18-rc2-utopic: does not boot

[Joseph Salisbury (jsalisbury)]

I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.

Can you test the following kernels and post back? We are looking for the first kernel version that exhibits this bug:

v3.13.11.6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.6-trusty/
v3.13.11.7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.7-trusty/

Thanks in advance!

[Konstantin (list-kseiler)]

Thanks. Looks like you selected the right two versions:

v3.13.11.6: everything works
v3.13.11.7: USB is dead after resume

[Joseph Salisbury (jsalisbury)]

I started a kernel bisect between v3.13.11.6 and v3.13.11.7. The kernel bisect will require testing of about 7-10 test kernels.

I built the first test kernel, up to the following commit:
73fc68b54a3768ce57f96e2fcf27a0fe3fad2fde

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1384041

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

Thanks in advance

[Konstantin (list-kseiler)]

Joseph, Thanks.

I tested the Kernel. USB was dead after resume.

Linux version 3.13.11-03131106-generic (jsalisbury@gloin) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #201410291902 SMP Wed Oct 29 19:04:24 UTC 2014

[Konstantin (list-kseiler)]

I decided to speed things up a little and continued the bisection on my own, compiling kernels on my machine directly.

The last good commit is 4a6c3031a7a34bfea80b84e9f657c1d07f21166a "mei: fix return value on disconnect timeout"
The first bad commit is fe5c234e529ff6fc0b4a79c088a1a6d3878ad4e6 "USB: Fix persist resume of some SS USB devices"

Looks like this patch that is trying to fix resuming SS USB devices is causing my SS USB devices to be dead after resume.

[Joseph Salisbury (jsalisbury)]

I built the next test kernel, up to the following commit:
d8e5976d3f4a01a45cf0abedb9923196f0371705

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1384041

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

Thanks in advance

[Joseph Salisbury (jsalisbury)]

You can ignore comment #19. Posted before hitting reload.

Great work finding the bad commit. I'll build a test kernel with commit fe5c234e529ff6fc0b4a79c088a1a6d3878ad4e6 reverted.

[Joseph Salisbury (jsalisbury)]

I built a Trusty test kernel with a revert of the following commit:
229be4d USB: Fix persist resume of some SS USB devices

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1384041

Can you test that kernel and report back if it has the bug or not?

[Konstantin (list-kseiler)]

Joseph, the test kernel you built seems to be good.

    USB: Fix persist resume of some SS USB devices

I'll update the bug with any feedback received.

[penalvch (penalvch)]

Konstantin, could you please test the latest mainline kernel 3.18-rc3 and advise to the results (3.18-r2 was found to be problematic for many)?

[Joseph Salisbury (jsalisbury)]

We received a patch from upstream:
https://lkml.org/lkml/2014/11/5/79

I built a Trusty test kernel with this patch. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1384041

Can you test that kernel and report back if it has the bug or not?

Note, for this test kernel you will need to install both the linux-image and linux-image-extra .deb packages.

[Konstantin (list-kseiler)]

I tested the latest kernel you built. USB was dead after resume.

Kernel version: 3.16.0-25-generic_3.16.0-25.33~lp1384041v1

I attached the syslog of the boot-sleep-resume-shutdown run.

[Konstantin (list-kseiler)]

Christopher, I also did a quick test of v3.18-rc3-vivid. The kernel didn't show the huge issues I had with rc2. But USB was still dead after resume.

[Konstantin (list-kseiler)]

Joseph, has there been any progress on this issue?

Just double checking that you're not waiting for enything from me. I think I tested everything you asked me to.

[Joseph Salisbury (jsalisbury)]

I built another test kernel with this patch. However, the value of PORT_ENABLE_WAIT was increased to 4000. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1384041

Can you test that kernel and report back if it has the bug or not?

Note, for this test kernel you will need to install both the linux-image and linux-image-extra .deb packages.

[Konstantin (list-kseiler)]

Joseph,
I tried the latest kernel you provided. It does have the bug (USB was dead after resume)

I attached the syslog.

[Joseph Salisbury (jsalisbury)]

I built one more test kernel with this patch. However, the value of PORT_ENABLE_WAIT was increased to 8000. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1384041

Can you test that kernel and report back if it has the bug or not?

Note, for this test kernel you will need to install both the linux-image and linux-image-extra .deb packages.

I'll give upstream some feedback on the results of this patch with that value of PORT_ENABLE_WAIT.
