No HDMI output while unlocking encrypted root on linux 6.12.11 kernel

[Tim Makarios]

I have an encrypted root partition, and on booting, it asks me for the passphrase to decrypt it.  This was shown on the screen when I was using the 6.6.47 kernel, but on the 6.12.11 kernel, nothing is shown on the screen at all until I've successfully typed the passphrase and it's started booting.

 

Here's the armbianmonitor -u output for the working 6.6.47 kernel: https://paste.next.armbian.com/suporamoqe

 

And here's the output for the not-quite-so-working 6.12.11 kernel: https://paste.armbian.de/cuxaxoweci

 

This isn't a huge deal for me, since I usually close my eyes while typing the passphrase anyway, but it means I have to guess when it's ready for me to type the passphrase, and guess how long to wait before concluding that I typed it wrong, and need to try again.  Also, it might bother other people more than it bothers me.
