Title:
[8086:4238] iwlwifi: fail to flush all tx fifo queues Q 0
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I have a Lenovo ThinkPad X201 Tablet with an Intel Centrino Ultimate-N
6300 AGN wireless card. Ever since I have upgraded to Ubuntu 13.10
from Ubuntu 12.10, I keep experiencing this annoying issue on wireless
networks with multiple APs: a TX queue gets stuck, and the wireless
card cannot send any packets. The Wi-Fi LED constantly flashes, and
sometimes, it becomes nearly impossible to restart the wireless card
using Fn+F5.
The NetworkManager connection is setup as follows:
SSID: IllinoisNet
BSSID: DA:BE:76:xx:xx:xx
Security: WPA/WPA2 Enterprise
Authentication: Protected EAP (PEAP)
CA Certificate: /etc/ssl/certs/AddTrust_External_Root.pem
PEAP Version: Automatic
Inner Authentication: MSCHAPv2
Notice that I have manually specified a BSSID to force the system to
use only one AP (since I have not found a way to reduce the roaming
aggressiveness on Intel wireless cards in Linux).
Attached is the Wireshark log and the syslog output while TX queue 0
is stuck.
