Public bug reported:
Last working version: 5.13.0-20-generic
Not working: 5.13.0-21-generic
Notebook: Dell XPS 15
Wifi adapter: Qualcomm QCA6390 Wireless Network Adapter [AX500-DBS (2x2)] (rev
01)
After booting 5.13.0-21-generic the wifi adapter is not detected anymore
(missing from lspci).
I have to turn off the computer and boot an older kernel. Simple restart
doesn't work.
With 5.13.0-20-generic the driver is just loaded fine:
