I tried that one, but it grinded the whole system to a halt. Lines builtup from the kernel message was about 1 line per 5sec (!!!!) At the end it stopped at [ 4.688226] ACPI: 3 ACPI AML tables successfully acquired and loaded But it was far from 4sec that it took to arrive there, more like 5min! After that nothing moves. I attach the screenshot when it was hanging at the end/ > - If it boots with UEFI, does the kernel parameter "efi=noruntime" > work around the problem?

I have the same hangs ... nothing goes on after Loading initial ramdisk.
