It looks like it's not actually loading the firmware in the 2nd one, it says it's already loaded. I wonder if you can force it to reload the firmware each time?

I also executed sudo dmesg | grep -Ei 'iwl|firmware|ucode|Linux version' command for Debian and there also row "Firmware already loaded":

And I have idea why when I restored MX from snapshot, first output of above mentioned command gives output:

Code: Select all

[   96.293972] Bluetooth: hci0: Waiting for firmware download to complete
[   96.294947] Bluetooth: hci0: Firmware loaded in 1497466 usecs

The reason is when I created snapshot, I have only RTL8822BE, and AX200 was installed later..

Darn, Tom seemed grumpy, but knew what he was talking about. Don't hang down your head, Tom!

Anyway, the last two lines about loading the AX200 firmware seem to me saying that it found version 15 firmware, but 20 was already loaded. This is pretty normal when you want firmware to cover multiple kernel versions.

Also, firmware files aren't being downloaded from the net, but into the device from the files on your machine, in case anyone is confused.

Something very odd in that firmware saying that it IS already loaded. I am going to suggest to update your linux-firmware to the very latest. There are a number of things that have been updated since your version

Code: Select all

firmware-iwlwifi:
  Installed: 20230210-5

and the latest linux-firmware shows updates to that package as late as 20250311 !

You can update your linux firmware as follows:
...

Code: Select all

wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20250311.tar.gz ; tar -xf linux-firmware-20250311.tar.gz ; cd linux-firmware-20250311 ; sudo cp -R * /lib/firmware/ ; sudo update-initramfs -uk all

Done at live usb. But after power off/on nothing changed. 'apt-cache policy firmware-iwlwifi' output is same:

Code: Select all

... firmware-iwlwifi:
  Installed: 20230210-5

Checked same command at Debian (hard drive). Result same, but bluetooths works fine.
UPD: exact output from Debian:

There also appears to be a number of posts about this model having issues with "disappearing bluetooth". Some are resolved with different drivers (windows), some with bios updates.
If the above firmware update doesnt help this situation... and a bios update also does not resolve it.. you may find the best solution is to pickup that bluetooth adapter I linked back a few posts ;-/
...

The most problem with bluetooh at above links about Wndows.. My both adapters work perfectly at Windows, Debian, Ubuntu..
Also very seldom, my adapters work at MX. Usually it happens after I restart after Windows or Debian or when I write new ISO, and first boot from it...
Later, in 5 .. 10 .. 30 minutes bluetooths fails and I can observe next:

USB device disappears and even restart can't help. After that I need boot to windows or Debian..

It would not help to do this on a live usb, you would have to do it on your regular install.

Something is being turned on or off at the windows run. And you DO have fast boot turned off right?

Is there anything in your bios that has bluetooth? any mention of it?

Fast boot is disabled at Windows.

I can only enable/disable bluetooth from BIOS.
