I tried (1) and the problem is not gone with that kernel. What I did was this:
1. boot the kernel
2. switch to console (CTRL+ALT+F2) to prevent locking up in plymouth
3. try to unload the libertas_sdio module (fails with kernel stack
dump, but prevents timeout spamming)
4. # systemctl start powerd.service
5. show the systemd-journal to check that powerd has been started
6. wait until powerd kicks in
7. take a picture of the screen:
This does not tell me a lot. Let me know if you want me to try booting
(which kernel?) with 'no_console_suspend' and do some more tests.
Unfortunately I do not have a working serial console setup atm
(missing the USB-cable).
