Misterious Kernel Panic in corporate WPA2 network (Arch Linux)

[Liarra]

Hello there, I'm not a very experienced Linux user, so sorry in advance for stupid questions/assumptions/lack of technical information.

The issue is the following: in one particular spot of a university library my Arch system gives me a kernel panic. Sometimes it happens upon connection establishing, sometimes a bit later, but always around that time.

I'm pretty sure it has something to do with wireless; I tried to disable wireless in NetworkManager and the problem did not occur for ~30 minutes I was on the spot. Again, with wireless on it happened almost instantly after connection had been established. Also for some reason this issue occurs only in one spot, probably with specific wireless router. Unfortunately, I don't have access to it and it seems to be hidden.

My machine is Lenovo Youga 13 with Arch Linux. uname -r gives me: 3.13.6-1-ARCH

Please tell me if there is any other information I could provide. Thank you.

How did you obtain the driver for the RTL8723AU? If it was from this repo, then post the output of 'git describe'.

[Liarra]

[nina@arch rtl8723au]$ git describe
fatal: No names found, cannot describe anything.
[nina@arch rtl8723au]$ git describe --all
heads/master

Were you in the directory with the driver source? If so, then you likely did dot get the source via git.

The reason I wanted the git info is that your traceback points to a nonsense location. Unless you get the source via a 'git clone' command and can tell me exactly what version you are running by a meaningful 'git describe', I will be unable to help you.

Yes, I got it from this repository with git clone.

[nina@arch rtl8723au]$ git describe --always

This seems to be the commit number. It is a master branch.

I just committed some code to check for a special condition that might be causing the problem. If it happens, a message will be logged, but it will not oops.

Yay, it works! Thanks :)
