Title:
[Samsung NP900X3C-A05DE] iwlwifi :01:00.0: fail to flush all tx
fifo queues Q 2 with Centrino Advanced-N 6235
I'm sorry to inform even with 3.17.0-031700rc3-generic the problem does not

after about 15 minutes usage I got bad connectivity and found the following in
dmesg.

advise to the results?

order to identify the fix commit. Could you please do this following
