Hi Oleksij,
I have tried to recover the full dmesg, but it seems to be lost.
I am not sure if it disappeared with during the last reboot or was not
synced back to the flash due to the kernel panic.
I tried to reproduce the kernel oops, but get stuck with the problem I
mentioned in my other email.
Is there a way of printing / tracing bad packages, so that when this
crash occures the next time, I have hopefully more information
available?
Also, just for completeness, the issue that stops me from trying to
reproduce the kernel oops:

Hi Oleksij,
Thanks for the reply.
For this test I am running it in managed mode.
Can you please send complete dmesg. May be there are some previous
messages can give some hint.
Right now i assume that some bad packets are not filtered out.
Beside, do your source have commit d21ccfd0a60e "ath9k_htc: fix random

Hi,
While running a iperf test, I experienced a kernel Oops in the Wifi
/
crypto module. I tried to reproduce it, but only managed to do it
once
so far.
Hmm.. do it run in monitor or AP mode?
I ask, because in combination with your other email i would assume
that
not all corrupt packets are filtered.
The system is:
BeagleBone Black, Rev C
Kernel 3.17.0-bone4 from BeagleBone
Using debian Jessie for Arm
Wifi: Netgear WNA1100

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Scenario:
I am running
iperf -c 192.168.1.32 -i1 -t300 -w1000k
to test network performance
During this test I got the following kernel Oops (see below).
Is this a known issue (I couldn't find anything related on Google so
far)?
Kind regards,
Jens
