Kernel 6.12.1 on 42710 issue at boot

General Discussion
1

This issue already happen in the past.

On a fully encrypted disk, the new kernel 6.12.1, don’t read the keyboard entries (the password, to decrypt and continue booting).
This was already resolved by @btwarden on June 25th : Not start new kernel - #8 by angusyoung1794 :

“I believe I’ve tracked down the problem to kernel module compression – specifically, during initrd, the kernel isn’t able to decompress modules because it was expecting to use external utilities. I’m reworking the initrd to have the keyboard driver modules already decompressed.”

Please, consider this fix for the next release.
Thanks for your efforts!

Interesting. I was wondering why OS would completely stop on login.

I thought it was because I use a USB keyboard and mouse.

I also, thought it may be the windows 10 boot HD in the computer until I removed it and it still occurred.

In the old DOS days, I would make sure the drivers needed for login would load in high mem block during boot up. Dose Linux also do this?

we made a change to move the keyboard drivers into the kernel (rather than as modules) – sounds like this does not work for you

are there any error messages that indicate what is going wrong maybe?

Hi @arjan, no, no error at all. I just select the kernel at boot, and when asks for the passphrase to decrypt the disk, I just type it in the keyboard, and no echo of ‘******’ is showed on the screen. I type it completely, and, when I press enter, there’s no action.

Can you tell us what keyboard you have (lsusb)? Can you try adding debug to the kernel command line (man clr-boot-manager for details) to see if there’s anything useful?

I don’t have an external keyboard:

I will try to add some debug as soon as I can.
