Surface Pro 2 wifi crash

[Tom]

System hangs as soon as any network traffic is generated from wifi adaptor.

think i may have caught the crash trying to install wireshark via the console (ctrl + alt + f1)

Tom, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/Kernel/MainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test 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 bug 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 XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, 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 upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Thanks Christopher,

I tried with v4.1-rc6-unstable and problem still exists.

[penalvch (penalvch)]

Tom, the issue you are reporting is an upstream one. Could you please report this problem to the appropriate mailing list (linux-wireless) by following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel ?

Please provide a direct URL to your e-mail to the mailing list once you have made it so that it may be tracked via http://vger.kernel.org/vger-lists.html . It can take a day for the new e-mail to show up in the respective archive.

Thank you for your understanding.

Bug 69661 - mwifiex_usb on MS Surface Pro 1 is unstable
https://bugzilla.kernel.org/show_bug.cgi?id=69661

>Most of the posted patches, found at top of page, can be found in the linux-next branch on kernel.org. To download/clone this repo just run the command:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

Some guy seems to have patched for this issue on the 'next' version of the kernel.
They report it does not work perfectly but woks reliably.
I will git clone and build and try by myself.

[kenokabe (kenokabe)]

I built the latest stable kernel 4.1.6 with the patch under Debian8.1 for deb packages.

Incorrect repo name, link modified...

[Tom (vsboost)]

Just installed 4.3-rc2-unstable and wifi works now.

[penalvch (penalvch)]

Tom, the next step is to fully reverse commit bisect from kernel 4.1-rc6 to 4.3-rc2 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

Thank you for your understanding.
