Wi-Fi stops working after upgrading from -12- to
linux-image-5.10.0-13-amd64 (iwlwifi: probe of 0000:00:14.3 failed with
error -110))
So in order to get more debug info, I set `loglevel=3` in grub in the
kernel command line.
That changed two things:
* now while booting I get to see the line on screen:
iwlwifi 0000:00:14.3: firmware: failed to load iwl-debug-yoyo.bin (-2)
That wouldn't get displayed previously when booting without `loglevel=3`
* now Wi-Fi actually works!
kernel logs say:

Repeatedly switching back and forth between booting kernel ...-13 with or
without `loglevel=3` will alternate between working and non-working Wi-Fi.
