iwlwifi 0000:01:00.0: Failed to load firmware chunk!

Asked by Serge Kopalkin

Hi, my wifi stopped working recently, I'm on 15.04, my wifi card is intel 7260
Now i'm now sure if it's an ubuntu bug, misconfiguration issue, kernel bug, or hardware failure.
Where is the right place to file such a bug?
Thank you!

Below are some logs:

Could also try:

echo "options iwlwifi bt_coex_active=N" | sudo tee /etc/modprobe.d/iwlwififix.conf > /dev/null

reboot to test

Thanks for the answers!
Looks like it's a driver related issue, i've sent an email to the folks from intel iwlwifi working group.
Hope they will shed some light on this issue.
