Hi,

I've recompiled my kernel[^moreinfo] of my raspberry pi 4 than run under Devuan rpi

some of the command used on the rpi to compile

\ In addition to have enabled some cipher/algorithm in the kernel config I have set a string ( TESTversionA ) in CONFIG_LOCALVERSION , may be I shouldn't have :/ ?

I'm currently following this guide LUKS on Raspberry Pi ( for context my related lemmy post )

So now that the kernel has been updated, the cryptsetup benchmark -c xchacha20,aes-adiantum-plain64 command is successful

So in order to enable luks in initramfs I'm following the preparing-linux section of this guide.
\
\ we can read:

initramfs has to be recreated

I followed the guidance and edited the initramfs-rebuild file to match my setup

initramfs-rebuild file

\ and when I run mkinitramfs -o /boot/broadcom/initrd.gz I got

grep: /boot/config-6.1.93TEST+: No such file or directory

I've did

 bash

    
cp /RaspKernel_6_1_y/linux/.config /boot/config-6.1.93TEST+
mkinitramfs -o /boot/broadcom/initrd.gz


  

and it seemed worked. I've edit the remaining files

• /boot/broadcom/cmdline.txt
• /etc/fstab
• /etc/crypttab

rebooted. Landed in the initramfs shell as expected

but benchmark -c xchacha20,aes-adiantum-plain64 is no longer successful :'(

Cipher xchacha20,aes-adiantum-plain64 (with 256 bit key) is not available

Any ideas where might lay the problem ?

Thanks.
