Bluetooth device sometimes vanishes after booting Tumbleweed - needs BIOS on/off cycle to come back

User-Agent: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:68.0) Gecko/20100101 Firefox/68.0
Hardware: Lenovo V340-IWL, i5-8265U, 8GB RAM, NVME, Qualcomm / Atheros WiFi / BT
Reference: PartedMagic Live (5.2.9)
WiFi / BT just work with PartedMagic. With the latest TW 2019-12-21 WiFi works, but the BT device vanishes after every single boot and does not come back until I disable WLAN in the BIOS, reboot, enable WLAN in the BIOS.
PartedMagic does not "kill" the BT device at all.
Could it be that some Firmware setting kills BT ?
Steps to Reproduce:
1. "fix" BT / WLAN in the BIOS
2. Boot TW
3. BT device gone until Step 1.

I need to do some more testing.
So for now I'll claim "sometimes" with TW, never with PartedMagic as the frequency of occurrence of this problem.
Please attach dmesg with PartedMagic and dmesg of a TW boot which detects it and the subsequent failing boot.
Updating said machine to latest TW & testing again.
Lenovo has released a new BIOS, but unfortunately they only provide the flash utility for the MS stuff, so that won't happen any time soon.
If anybody knows how to get this stuff running with a WinPE USB stick, that would be great. Tried the X86 and AMD64 versions, doesn't run the .exe :-(
Well, that didn't help. Bluethooth still doesn't start.
0 wlan ...
1 bluetooth ideapad_bluetooth unlocked unlocked
2 wlan phy0
/sys/class/bluetooth doesn't exist
syslog: systemd: Condition check resulted in Bluetooth service being skipped
Once I have physical access again, I will make further tests.
Robert, any luck? TW is also on 5.7.x kernel now.
And Oliver asked for dmesgs both from TW and PartedMagic if you can provide them, please.
So far I haven't visited my far away relatives. They're not computer savvy, the laptop is just a "black box" for them. I can't expect them to do a lot of rebooting and debugging via a phone call. I can log into their machine, but then there's the Bluetooth headphone ... too many variables. Of course it doesn't have ILO / IPMI either. This is an on-site job.
There are 2 BIOS updates pending. Unfortunately Lenovo requires Windows for BIOS updates in their consumer grade laptops. Maybe W10-to-go on a USB-stick will help there ... I'll find out.
I will report back after I've made the trip and hopefully made all of the updates happen. Sorry for the delay.
As the BT adapter is connected via USB, I will try the same thing as on my other laptop, i.e. I will disable LPM on that laptop. Maybe this helps in this case as well - if I'm lucky.

Robert, any news here?
During Xmas holidays I updated the BIOS to the latest version available from Lenovo (ATCN45WW) + TW updates.
It seems to work now.
