 Posted: Tue Jun 09, 2020 3:46 pm Post subject: New box initial kernel messages garbled |
 |
|
A few months back I replaced the box I use as a server and restored the existing system onto the new disks. The only major difference was that the new h/w is UEFI and I had to make the boot partition vfat. All that seemed to work and when I boot I get the BIOS screen, followed by the Grub2 menu but when the kernel boots the initial messages don't appear, just a lot of static in the top quarter of the screen. Then the frame-buffer module (?) is loaded and everything is in HD across the whole of the 1920x1080 HD screen, like it was on the old system. So I wasn't too bothered by the initial fubar messages until I rebuilt the system on a new partition which has an error and I can't read the messages!  The kernel console settings are the same as they have always been and so are the Grub parameters and the kernel command parameters:

Any ideas what I should tweak?
Thanks
