Thanks for the tip. Disabling caam_jr helps and now I can use iwd with kernel 6.5. I did not have to blacklist caam:
$ cat /etc/modprobe.d/iwd.conf
blacklist caam_jr
$ lsmod | grep caa
caam 20480 0
error 20480 1 caam
I’m not using official image, but one one built by myself, using btrfs on LUKS. I’m haven’t used system with blacklist much; I want to test performance because btrfs scrub was running slowly today after that change. I’ll let check it and provide more details if I have them.
