system crashes... wpa_supplicant

Post by capponz » Sun Dec 03, 2017 2:40 am

Hi, my system mint 18.1 Mate on an Acer notebook crashes quite often.
The last entry in var/log/syslog showed the last two times:

Code: Select all

Nov 29 09:35:01 deep-thought CRON[2363]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)
Nov 29 09:37:34 deep-thought wpa_supplicant[1041]: wlp2s0: WPA: Group rekeying completed with c8:0e:14:cb:fe:ce [GTK=TKIP]


Dec  3 12:25:01 deep-thought CRON[32019]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)
Dec  3 12:26:42 deep-thought wpa_supplicant[1062]: wlp2s0: WPA: Group rekeying completed with c8:0e:14:e8:de:51 [GTK=TKIP]
I found a crash Mint entry in some forum and they mentioned to deactivate bluetooth. Which seemed to help. but at the end it did not.

My graphic card is:

Code: Select all

capponz@deep-thought ~ $ inxi -G
Graphics:  Card: Intel Atom Processor Z36xxx/Z37xxx Series Graphics & Display
           Display Server: X.Org 1.18.3 drivers: intel (unloaded: fbdev,vesa) Resolution: 1366x768@59.99hz
           GLX Renderer: Mesa DRI Intel Bay Trail GLX Version: 3.0 Mesa 17.0.7
I have no further ideas.
please help

Please run the following command from Terminal and post back the result:

Code: Select all

inxi -Fxz

From what I've gleaned about wireless encryption, TKIP should NOT be used with Linux because of the problems it causes. I would suggest, if you have access to the router, changing your cypher to CCMP only.

Thanks for the reply.
but this does not fix my problem...
your suggestion is more a security recommendation, right?

thanks

My understanding is that TKIP causes connection problems.

Yes but connection problems should not cause freezing the system, right?
That's what my initial post is about.
My system freezes completely. even REISUB does not work when this occures.
cheers

I see your running Mint 18.0 Sarah (not 18.1 Serena). The Kernel 4.4.0-21 is pretty old and has a lot of patches up to the current 4.4.0-101 Kernel (current fix level for that old Kernel).

You might want to try updating the Kernel level as a start from Update Manager as a test. If you want to stay with 4.4, that's OK. Just getting to the current fixed level should give some elimination of bugs from the past 18-24 months of updates as the cause of the freezes.

Well, the Bay Trail support might be the sticking point and what Kernel gives best support. There are plenty of articles and blogs discussing Bay Trail problems with Linux. This article is a year old.

http://opensourceforu.com/2016/10/ubunt ... rocessors/

I'd hoped that updating to a more recent 4.4 patched Kernel would help.

I know you're using the old Mint 18.1 release. Was there a specific reason you didn't update to Mint 18.2 or 18.3 with newer Kernels (and updated firmware)?

FYI.....the wpa_supplicant message on rekeying are normal and periodic. That's not eliminating Wifi as a source of problem, just not a definite "That's the problem" cause.

When the problem occurs, are you simply getting freezes/lockups, or are there other symptoms?

Hi ClixTrix,
thank you for your quick reply.
well, the only reason I used the "older" version was that I had a DVD of it and knew it's long term supported. :?
The system freezes without any previous symptoms. the system freezes and not even REISUB has any effect.
No matter what I'm doing...Gimp/Inkscape/web browsing...
I need to read into the "bay trail" options.
I'm happy to change the OS/version if the notebook stops freezing.
Are there Mint versions supporting bay trail? What would you suggest?
I'm lost right now.

Thank you very much

Linux Mint is based upon Ubuntu and generally follows the releases of their LTS versions every two years, e.g. Mint 18 tracks with the release of Ubuntu 16.04 and each supplemental update at about 6 month intervals. The recent release of Mint 18.3 follows the the Ubuntu 16.04.3 LTS released last July with Kernel 4.10 and is the last release of Mint 18. Ubuntu will release 18.04 next April and Mint will release 19.0 around June 2018.

From my checks the Ubuntu 16.10 Yakkety Yak (from that article on Bay Trail) came with Kernel 4.8. That's also the Kernel that came with Mint 16.2 released last June and was probably also used in one of the Ubuntu 16.04 LTS cycle updates.

https://wiki.ubuntu.com/YakketyYak/ReleaseNotes

However, the Kernel 4.8 was a short-term support kernel and no longer is getting updates. You could try that Kernel for a test from Update Manager.

The more current Kernel released with Mint 18.3 is 4.10 and came bundled with that release.

You can also use Update Manager and update your install to the current release of Mint 18.3 and the 4.10 Kernel.
