Hello everyone, I’m sorry that this, of all things, is the first post I create after my introduction, but I ran into some problems I couldn’t solve by myself.
First: My laptop (a Lenovo IdeaPad 5) has a WiFi card from Realtek, namely an RTL8852AE. I used to easily get this card to run by connecting my phone via USB, install rtw89-dmks-git from the AUR, and finally doing a quick sudo modprobe rtw89pci. Now, I’ve seen that after every kernel change the thing has to be rebuild, so I did as instructed and had yay rebuild it—at least I assume that’s what I did, because yay asked me if I wanted to “clean build” it and I told it to do so.
Now, however, I can’t activate it, as the modprobe command just returns an error:
sudo modprobe -v rtw89pci
insmod /lib/modules/5.16.0-arch1-1/updates/dkms/rtw89pci.ko.zst
modprobe: ERROR: could not insert 'rtw89pci': Exec format error
This means that my laptop currently has no WiFi. I can work around that, but it is a tad annoying—aka I’m a bit freaked out. 
Second issue: Before the most recent updates, booting and shutting down would show just a few messages, usually something about a dog that didn’t stop. I like dogs, so I never worried too much about it. “Let it play,” I thought. Ahem … Anyway, ever since today, my screen is flooded with messages during boot and shutdown processes. Most of them, again, seem fine, like:
Unmounting this and that …
Finished unmounting …
Detaching this and that …
Finished detaching …
etc. It’s a bit unusual to see all of this spelled out to me, but it’s nothing I should worry about, I think.
What I do worry about, however, is that the laptop won’t turn off on its own any more. After all these messages it now stops at kvm: exiting hardware virtualization and it stays that way, until I hold down the power button.
If anyone has a great idea or two on how to fix these issues, I’d be very grateful.
Here is some information about my system:
