Title:
ath10k_pci (QCA9377) firmware crashes when charger plugged
Status in linux package in Ubuntu:
Incomplete
Status in linux-firmware package in Ubuntu:
New
Bug description:
This issue only occurs when charger is plugged. My network adapter is
built-in in my laptop (it's not an usb).
I'm also connected in a 5ghz network, so i suggest using it.
=== How to reproduce ==
* shutdown your laptop (do not use reboot option);
* connect charger to laptop and turn it on; (the firmware should start and
connect to the 5ghz network)
* If no error is thrown, continue using your laptop and your wlan device. It
took me about 5 minutes to get a "firmware crash" error with code "-11".
* If the firmware crashed, reboot (using shutdown command) your laptop with
charger plugged in.
You might similar error: "device descriptor read/64, error -71"
* Temporary fix: Unplug the charger and reboot using shutdown command (two
times as it might not work for the first)
