GPU & disk encryption?
« on: January 07, 2023, 12:09:01 pm »
I flashed the AMD firmware to the BOOTKERNFW, and can see the Petitboot screen via the AMD GPU! However, when the OS boots, it goes dark for a few seconds, then a cursor appears. Only via the serial display via the BMC web interface am I able to see the prompt to unlock the disk to resume booting. Trying to enter the password on the keyboard doesn't work. Is there a way around this, so I don't need another computer to boot the encrypted disk? I used Debian's auto formatter, so /boot is unencrypted, and LVM has the encrypted swap and root partition. I wouldn't be opposed to having a way to inform Petitboot or BMC of the password somehow.

I have a somewhat similar system and solved the problem with
Code: [Select]
modprobe.blacklist=ast video=offb:off console=tty0.

I've also found I get "more" output if I manually select the kernel I want to boot from the Petitboot menu rather than letting it autoboot.
