Title:
Centrino Advanced-N 6235 wireless connection on Dell XPS 13 crash with
"iwlwifi: fail to flush all tx fifo queues"
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
After some activity, the wireless connection on my Dell XPS 13 laptop drops and I have to reboot to have it working again.
I had this bug with ubuntu 12.04 preinstalled by Dell. I had done a 13.04 fresh install to try to solve the problem, but with last kernel (3.8.0-13.23) after some time the connection eventually drops. I can't restore it without rebooting the entire system.
It always happens with
[] iwlwifi 0000:01:00.0: fail to flush all tx fifo queues
in dmesg
The network controller is:
01:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24)
I think this bug may be the same of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/836250 , but may also be unrelated because:
1) none of the solution proposed for #836250 works for me. I tried some iwlwifi module options (11n_disable=1, swcrypto=1, bt_coex_active=0) and turning off power managment (iwconfig wlan0 power off).
2) I seems to me that the patch from Intel attached in #836250 is already included in ubuntu 3.8.0-13.23 kernel. If it is correct, then that patch does not solve my problem.
