I can't reproduce this issue with any of my Bluetooth adapters (I tested
with 6 different ones). Could you get us the hcidump of what happens
when bluetoothd tries to switch on the adapter for the very first time?
Probably you'll need to disable starting of bluetoothd when your system
boots so that you have the chance to run hcidump first. Additionally, if
possible, could you enable dynamic debug in your kernel and get the logs
from hci_core.c and hci_event.c? Typically you'd enable this with
something like:

echo 'file hci_event.c +p' > /sys/kernel/debug/dynamic_debug/control
echo 'file hci_core.c +p' > /sys/kernel/debug/dynamic_debug/control

Hopefully those logs will give some better idea of what's going on since
the logs provided so far aren't really helpful.
