linux-firmware 20220329.git681281e4-0ubuntu1 used by Ubuntu 22.04 does not contain drivers for some Atheros WiFi/Bluetooth chipsets, which were included in the previous Ubuntu releases.
The package is missing some files from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree, specifically:
- ar3k (whole directory, was present in impish, missing in jammy)
- ar*.fw - firmware for AR7010, AR9170 and AR9271 (can't find in the impish version)
Because of that Bluetooth can't be enabled and WiFi is unstable on devices equipped with Atheros chipsets. In my case the following errors are reported by dmesg:
[ 3.653613] usb 1-1.1: Direct firmware load for ar3k/AthrBT_0x11020000.dfu failed with error -2
[ 3.653619] Bluetooth: Patch file not found ar3k/AthrBT_0x11020000.dfu
[ 3.653626] Bluetooth: Loading patch file failed
[ 3.653631] ath3k: probe of 1-1.1:1.0 failed with error -2

I think bug #1970052 is the same problem.
