Hi,
I got several problems with coreboot on X220. I report them for you to improve coreboot. I's not important for me. If you need more details on a specific problem, tell me please.
This is a build from today 4.11 branch with seabios and memtest payload
I've got several boot media ready to test how coreboot behaves. that is an original DOS 5.0 installation, like 30 years old. a fresh Kubuntu 20.4 installation Memtest86 4.3.7 (latest BIOS version)
- DOS 5.0 does not boot, it stops just before the C:> prompt - Kubuntu 20.4: systemd-udevd runs amok all the time. this might be because it tries modprobe nvidia-uvm. - Kubuntu 20.4: Shutdown does not work AE_NOT_FOUND - Kubuntu 20.4: reboot just switches off AE_NOT_FOUND - Kubuntu 20.4: Going to standby does not work. Switches off the screen, but leaves on the CPU and cannot wake up again. - Ctrl-Alt-Del does not work? - ESC for reboot from payload memtest or USB memtest just stops (crashes?) - access to CMOS using nvramtool does not work. complains about missing HAVE_OPTION_TABLE. but both USE_ and HAVE_OPTION_TABLE are set. this makes it impossible enabling the debug boot log for the board status database - I somehow cannot enter the grub boot menu. might this be related to missing graphics bios?
so, is this normal? I expected coreboot to be more production ready to be honest... :(
regards
Jan
