[Bug 1436891] Re: Cannot connect to any WiFi access point which runs wireless-N
Darren Peets, if the issue is still reproducible with the latest mainline kernel (4.1-rc1) then the issue you are reporting is an upstream one. Could you please report this problem to the appropriate mailing list 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.

OK, bisect result and a caveat: d88c8958dc13b4e4eb7fc57e3f06dc1c4abc7b1f is the first bad commit commit d88c8958dc13b4e4eb7fc57e3f06dc1c4abc7b1f Author: Emmanuel Grumbach Date: Mon Sep 1 09:50:14 2014 +0300 iwlwifi: bump firmware API version to 10 for 7000 and 8000 New firmware on the way. Signed-off-by: Emmanuel Grumbach :04 04 6fda9a82d01a59a4edeaee8d1fbeb2cce28eeecc 7b61151b4783bc2f3ae31a132fa36c80a84cb978 M drivers Now, what I tried to do during the bisect was the following: $ cp /boot/config-3.19.0-14-generic .config $ make oldconfig $ make clean $ make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-dpeets?? for ?? an increasing integer, and accepting all default settings for make oldconfig HOWEVER, for a vast expanse in the middle of this bisect range, building the kernel image failed if started from the 3.19 config file (here's one example): ... INSTALL debian/tmp/lib/firmware/cpia2/stv0672_vp4.bin INSTALL debian/tmp/lib/firmware/yam/1200.bin INSTALL debian/tmp/lib/firmware/yam/9600.bin DEPMOD 3.16.0-dpeets22 depmod: ERROR: Found 5 modules in dependency cycles! depmod: ERROR: Cycle detected: st21nfcb -> ndlc -> nci -> st21nfcb depmod: ERROR: Cycle detected: nci -> nci Makefile:1113: recipe for target '_modinst_post' failed make[2]: *** [_modinst_post] Error 1 scripts/package/Makefile:90: recipe for target 'deb-pkg' failed make[1]: *** [deb-pkg] Error 2 Makefile:1205: recipe for target 'deb-pkg' failed make: *** [deb-pkg] Error 2 I'm not in a position to do anything other than accept the defaults, and I'm not about to edit the config file on my own. So for perhaps half of the bisect steps, the starting point for .config was the previous bisect step's .config (without first checking whether a copied 3.19 version worked), or in a couple cases a config file from a known good 3.16 kernel after the 3.19 config file failed. This means that the starting point was not necessarily the same for all steps. If there are parts of this I should redo or check, config files you'd like (I didn't save them in general, but I have a few), or anything I can test, let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1436891 Title: Cannot connect to any WiFi access point which runs wireless-N To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1436891/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1436891] Re: Cannot connect to any WiFi access point which runs wireless-N
OK, I couldn't figure out how to build kernel versions, so I tried to do a commit bisect between 3.16.0-0.1 and 3.16.0-23.31. It didn't do what I thought it would. From what I can tell, it looks like 3.16.0-0.1 is good, but git bisect took it to be bad, and has been bisecting things *before* it. I might now have worked out how to get git to build a specific kernel version. The weather's supposed to be garbage tomorrow and I don't have all that much else to do, so maybe I'll have a chance to work on this a bit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1436891 Title: Cannot connect to any WiFi access point which runs wireless-N To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1436891/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1436891] Re: Cannot connect to any WiFi access point which runs wireless-N
Could the problem be related to kwalletmanager and password management system? When I try to connect to wifi then KWallet insists on being used. I select "Cancel" and the wifi network is not connected. I've noticed that KWallet takes the control of the system. In previous versions of Kubuntu, I could disable KWallet from systemsettings, but now I can't find this entry. After launching KWallet from the menu and from KWallet settings, I can disable it. But KWallet gets worse, it continues requesting to be used, and if I try to open it from the menu, KWallet freezes. In the end I decided to use it and set a password. The wifi connection was established but the connection falls at few seconds. >From LiveDVD I can not connect to wifi too, but KWallet is not open asking to be used in LiveDVD, but I do not know, maybe kwallet is intervening in the background too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1436891 Title: Cannot connect to any WiFi access point which runs wireless-N To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1436891/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1436891] Re: Cannot connect to any WiFi access point which runs wireless-N
Update: Bug exists in first Vivid version (3.16.0-23.31) that's readily available in pre-packaged .deb format. So I need to start building kernels, I presume, to check 3.16.0-0.1 (since I don't yet have a "good" kernel within Vivid) and bisect from there. I'm still trying to figure out how to build specific versions. Or, how to find a commit corresponding to the start of Vivid. I also tried Utopic's 3.16.0-34.45, and the bug is not present there -- I can connect to wifi N just fine with that one.

Darren Peets, the next step is to fully commit bisect from kernel 3.16 to 3.19 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

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 v4.0 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.
