Hi Philippe,
Tried your test with v5.18.0 on my desktop and both wifi/bt are still
avaible after reboot. The only problem is I need to insert btusb module
by command "modprobe btusb" to make BT workable.
I will check the issue on different platforms. If there are any
finding, I will let you know.
Regards,
Deren
