Since the kernel upgrade to 5.6.0-1048-oem my Dell XPS 13 9380 starts to hang
and finally freezes when I want to connect to my AV-receiver over bluetooth.
All consecutive versions > 5.6.0-1048-oem show the same behaviour, hence I'm
still booting 5.6.0-1047-oem currently.
The only HW change I did to my Dell XPS 13 9380 was changing my SSD to a
bigger Samsung SSD 970 EVO Plus 1TB, everything is as I ordered it.
Can somebody reproduce this issue?
