OpenBSD hangs on login

[Letni]

Hello,

OpenBSD 7.3 hangs at the login on my intel C3758 based custom board. On every power-up, OpenBSD runs without problem up to the login, but, after 2 second hangs problem begins here.

OpenBSD/amd64 (Anda.Intel) (tty00)

login: roo        <--- trying to login as root, after 2 sec it hangs.

I tried to upgrade OpenBSD version 7.2 to 7.3, the problem is same. I thought the problem might be from the version update and tried to download and install the new version directly. Nothing has changed, the problem persists.

I tested both legacy BIOS and UEFI but same in both. I don't have such a problem in version 7.2. What do you think could be the problem?
