Hi, the Intel(R) Dual Band Wireless AC 7265 is not a problem. the wifi is working ok. since reporting the bug, i can get my bluetooth headphones ok. but only after remove/forget and then rebooting. if i use a live 18.04 all works ok.
hopfully, i have attached the logs. regards chris On Tue, 2020-05-19 at 07:37 +0000, You-Sheng Yang wrote: > Hi, I happen to have the same Intel(R) Dual Band Wireless AC 7265 > [8086:095a] subsystem [8086:5010] hardware as you do, and Bluetooth > is > loading the same blob intel/ibt-hw-37.8.10-fw-1.10.3.11.e.bseq from > linux-firmware version 1.187, kernel 5.4.0-31-generic.
