Bluetooth and Network gone after update to Kernel 6.13

Since last summer I own a Minisforum Mini PC based on a AMD Ryzen 9 7940HS w/ Radeon 780M Graphics, which worked great so far.
After Kernel 6.13 was installed Bluetooth (including sound) and Networking was gone. The only way to get it back was to downgrade to 6.12.
I now waited until the first patch release of 6.13 but the problem persists.

Does anybody know of such problems? Arch is my GoTo since 10 years+ and I never had such base issues...

- I use a wired connection only, which is, according to lspci, a Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
- "ip a" does not show any network hardware
- there is no "/sys/class/bluetooth" directory anymore

Re: Bluetooth and Network gone after update to Kernel 6.13

Same issue with bluetooth here. No '/sys/class/bluetooth' directory so the bluetooth service doesn't launch. Also had to disable `NetworkManager-wait-online.service` because it times out. All that since the last kernel update.

Please post the full system journal from a boot with the issue.

OK, wrong logfile. Let me start over again...

Re: Bluetooth and Network gone after update to Kernel 6.13

Well, after updating to 6.13 and a reboot `uname -r` still returned 6.12.10-arch-1 - but with the issues mentioned above. I am confused - and the gist above is what???

Re: Bluetooth and Network gone after update to Kernel 6.13

Most likely the ESP was not mounted when the linux package was updated causing the mismatch between the running kernel and the installed modules hence the missing support.

Re: Bluetooth and Network gone after update to Kernel 6.13

OK, I go to the package cache dir and install the 6.13.2 version using "pacman -U ..." -> reboot -> no network, no bt. But "uname -r" still shows the older kernel version 6.12.10
Rolling back by installing 6.12.10 solved it. Something is wrong here...

Maybe mount changes during kernel version change to 6.13. but the others should stay the same. However, I am out for today

Re: Bluetooth and Network gone after update to Kernel 6.13

What is the output of the following:

file /boot/vmlinuz-linux
# umount /boot
file /boot/vmlinuz-linux

Also what boot-loader does the system use?

Re: Bluetooth and Network gone after update to Kernel 6.13

The boot-loader is using the kernel in the directory boot on the root file-system and not using the ESP.  mounting the ESP at /boot masks the kernel on the root file-system so it is not updated when the kernel package is updated.  You need to fix the boot-loader to use the ESP.

Re: Bluetooth and Network gone after update to Kernel 6.13

I see... I remember a boot loader error where the system could not find the kernel a few weeks ago. That makes sense.
Thanks for helping out
