@Liquid ;
Here is some feedback regarding the new kexec multiboot feature on OpenBH 6.0.4.
With OpenBH 6.0.4 installed in the flash memory, I am still encountering an issue where the recovery image displays nothing (bootlogo).
After flashing the new kexec multiboot, the system works properly, and I can successfully boot into the images stored in the various flash slots (pressed MENU on the remote, except for slot 0 which only displays the bootlogo) .
However, Enigma2 crashes systematically whenever I attempt to add EXTRA USB-slots.
I have attached my crash log to this post. Hopefully, it will help you analyze and fix this issue in future updates.
Thanks for your hard work.
