[Bug 1492850] Re: Dell pro venue 11 - No wireless connections after sleep

[Martin Pitt]

So obviously one of the quirks in /usr/lib/pm-utils/sleep.d works around
this kernel bug. We need to find out which. Can you please move the
files in that directory to some other place one by one and do a "sudo
pm-suspend" / resume cycle until it starts failing? That's the "magic"
hook then. Which one is it?

After that exercise, move the hooks back to /usr/lib/pm-utils/sleep.d/.

Thanks!

[Bug 1492850] Re: Dell pro venue 11 - No wireless connections after sleep

[Christopher M. Penalver]

stef.baly, given the results of how via upstart it works, but systemd
suspend doesn't work based on the method one initiates suspend, I've
added a systemd task to this report for review.

[Bug 1492850] Re: Dell pro venue 11 - No wireless connections after sleep

[Christopher M. Penalver]

stef.baly, to advise, hibernate, or hybrid suspend is treated as a
different problem, which would necessitate a separate report.

So, to recap the results regarding the scope of this report (suspend
only), with systemd, it works with pm-suspend. However, if you initiate
the suspend via the button, it doesn't?

Also, if you switch to upstart, it works either via the GUI, or pm-
suspend, correct?

[Bug 1492850] Re: Dell pro venue 11 - No wireless connections after sleep

[Christopher M. Penalver]

stef.baly, to advise, you don't need to apport-collect further unless
requested to do so. Especially with the mainline kernel installed as the
information is useless.

Despite this, could you please test the latest upstream kernel available
from the very top line at the top of the page from
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release
names are irrelevant for testing, and please do not test the daily
folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't 
boot into the OS) please make a comment in your report about this, and continue 
to test the next most recent kernel version until you can test to the issue. 
Once you've tested the upstream kernel, please comment on which kernel version 
specifically you tested. If this issue is fixed in the mainline kernel, please 
add the following tags by clicking on the yellow circle with a black pencil 
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[stef.baly]

Since a bios update (to A16), the bug is slightly different !
The wifi connection is perfect until the computer is suspend.
After a suspend,  wifi is disable and activating the wifi from network manager 
is impossible.  the computer must reboot ta enable the wifi or you fold the 
screen and then  when you reopen and wake up the computer the wifi is on !

[Bug 1492850] Re: Dell pro venue 11 - No wireless connections after sleep

[Christopher M. Penalver]

stef.baly, as per http://www.dell.com/support/home/us/en/19/product-
support/product/dell-venue-11i-pro/drivers/advanced an update to your
computer's buggy and outdated BIOS is available (A16). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

If it doesn't, could you please both specify what happened, and provide the 
output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.

  I try for a long time to set-up the wifi for my dell pro venue 11 v7130
  (wifi chipset Intel Corporation Wireless 7260). The wifi connection is
  perfect until the computer is suspend. After a suspend, even activating
  the wifi from network manager is impossible. After suspend even an exit
  doesn't reconnect to the wifi connection. It seems that the wifi chipset
  is off and it's impossible to wake up.
  
  Recently 15.04 has been update to 4.2 RC8. Nothing new !
  
  A file unload_modules has been created.
  /etc/pm/config.d with SUSPEND_MODULES="$SUSPEND_MODULES iwlwifi" without any 
effect.
  
  sudo service network-manager restart doesn't work too !

stef.baly, could you please boot into the Ubuntu kernel (not upstream), then 
execute the following command, as it will automatically gather debugging

[Bug 1492850] Re: Dell pro venue 11 - No wireless connections after sleep

[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
v4.2 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.
