Intel(R) Wi-Fi 7 BE200 320MHz, kernel warning and freeze
When I run sudo iwctl station wlan0 connect wifiname for the first time during a boot, iwctl would error
No matching method found
Failed to retrieve IWD dbus objects, quitting...
Running it for the second time would succeed and I can then dhcpcd wlan0. journalctl demonstrates the relevant kernel warnings for the first iwctl run.
I suspect that this is also related to the intermittent system freeze I am experiencing (https://bbs.archlinux.org/viewtopic.php?pid=2251387 )
