[-seabios for the GRUB part of the thread]
Could you please also check, if GRUB’s CBMEM console driver, and the the command cbmemc to display it need any updates?
Thanks, I wasn't aware that GRUB also had a driver for this. I'm happy to write a patch for it, but unfortunately I'm having some trouble testing it. I managed to build it after some effort, but I don't have hardware that supports it. Maybe you (or Vladimir?) could double-check that it works?
PS: Where can I get your S/MIME certificate, used to sign your email?
Sorry, that wasn't supposed to be there... I accidentally sent the first mail in here from the wrong account.
