I can confirm it's broken on AX211 as well. I'm using a Bluetooth
keyboard+headphones together with WiFi. Bluetooth on both devices works
fine for a while, but disconnects every few minutes (this is manifested
by the keyboard getting "stuck" or the sound stream becoming garbled)
Attaching some system information+logs below. They key point to note is
that every time this happens, these two lines are logged:
Apr 03 11:36:40 kernel: Bluetooth: hci0: Hardware error 0x0c
Apr 03 11:36:41 kernel: Bluetooth: hci0: Retrieving Intel exception info failed
(-16)
Sometimes the error code is different:
Apr 03 12:32:37 kernel: Bluetooth: hci0: Hardware error 0x0a
Apr 03 12:32:37 kernel: Bluetooth: hci0: Retrieving Intel exception info failed
(-16)
Using suggestions from another thread I've tried disabling power
management on the adapter by adding these lines to
/etc/modprobe.d/iwlwifi.conf and rebooting:
options iwlmvm power_scheme=1
options iwlwifi power_save=0
But that did not solve the issue.
