Hi everybody,

I updated openSuse Tumbleweed 20230806 with a bluetooth keyboard 
attached to the PC. After the update to 20230808 and rebooting bluetooth 
was disabled and it was impossible to enable it again. Before the update 
bluetooth was working fine.

The attached bluetooth keyboard caused the bluetooth module being added 
to initrd. However, the corresponding firmware for MT7922 is not added.

dmesg shows:

[    4.368031] bluetooth hci0: Direct firmware load for 
mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin failed with error -2

In fact the file is present on the system

ls -l /usr/lib/firmware/mediatek/BT_RAM_CODE*
-rw-r--r-- 1 root root 512104  3. Aug 17:36 
/usr/lib/firmware/mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin.xz
-rw-r--r-- 1 root root 343052  3. Aug 17:36 
/usr/lib/firmware/mediatek/BT_RAM_CODE_MT7961_1_2_hdr.bin.xz

but missing in initrd

lsinitrd | grep BT_RAM_CODE
-rw-r--r--   1 root     root       343052 Aug  3 17:36 
usr/lib/firmware/mediatek/BT_RAM_CODE_MT7961_1_2_hdr.bin.xz

Manually adding the file to initrd makes bluetooth work again.

I reported the bug here
https://bugzilla.suse.com/show_bug.cgi?id=1214133
and was requested to report here.

If I can be of any help or you need further information please let me know.

Thanks and kind regards

Jürgen
