Bug#1028116: linux-image-6.0.0-4-amd64: Bluetooth no longer working with Mediatek MT7921K chipset

2023-01-26 Thread Matthew McAllister 

Hi again,

I found the time to tinker on my computer the past week. I installed 6.1.4-1 
and 5.19.11-1 and neither kernel them worked; eventually I came to the 
conclusion my hardware is faulty. There's a thread in debian-user about it.

Thank you for your help; you should close this report as I no longer have 
reason to believe this is a software issue.

Bug#1028116: linux-image-6.0.0-4-amd64: Bluetooth no longer working with Mediatek MT7921K chipset

2023-01-07 Thread Matthew McAllister 
Sorry for my mistake. I upgraded to 6.0.12-1 and still no bluetooth. I 
additionally downgraded to 5.10.149-2, and that version had no bluetooth 
and no wifi support either. I wasn't able to even install 5.19.11-1; I 
suspect 5.19 may have been the last version I had installed where 
bluetooth actually worked.


I don't know how to install experimental kernel versions on testing, but 
I'm willing to try it out or compile it myself.

Dear Maintainer,

Bluetooth is no longer usable with this chipset on this kernel version.
/sys/class/bluetooth is not present after booting or rebooting. There are no
lines relating to bluetooth in dmesg. Here is the relevant part of lsmod:
mt7921e32768  0

cfg80211 1118208  4 mt76,mac80211,mt7921_common,mt76_connac_lib

WiFi *does* continue to work with this chipset. Only bluetooth seems to be
affected.

As 6.0.8-1 is not the most recent kernel in testing, can you test with
6.0.12-1 as well, or ideally even better with 6.1.2-1~exp1? Does the
problem persist there?

If yes, would you be able to bisect against an older known working
kernel version to identify where the problem arise and got introduced?

Regards,
Salvatore
