iwd broken after kernel update

If I try to update my kernel to the latest version, I get crypto errors when trying to start the iwd service:

Jun 02 18:40:05 h systemd[1]: iwd.service: Main process exited, code=exited, status=1/FAILURE

And so I am unable to connect to the internet with this new kernel. I downgraded the kernel, and it works again. Any ideas where the issue might come from ?

Re: iwd broken after kernel update

Can you give a full journal for a affected boot?

journalctl -b -1 | curl -F 'file=@-' 0x0.st

use -1 for the last boot, -2 for the one before that etc.

^ this expects that the drive is writeable. otherwise, you'll have to pipe it to a file on a usb drive or so while booting the new kernel, and then upload it:

journalctl -b 0 >/on-some-usb-drive/temp.txt
curl -F 'file=@-' 0x0.st < temp.txt #this one while on the old kernel/other PC

I suspect you are somehow unable to load kernel modules, leading to a filesystem mount problem or such, which somehow doesn't make sense since the rest seems to be working properly.

Re: iwd broken after kernel update

uname -a
pacman -Qs kernel
modinfo crypto-aes

Edit: run that on the disfunctional kernel
