(In reply to Borislav Petkov from comment #9) > You can make a video of the boot and upload it somewhere so that I can > take a look at what exactly happens. I have just sent to your e-mail address a link to the video (MKV, x264), which includes: (1) boot with the default settings; (2) boot without "quiet"; (3) boot with "dis_ucode_ldr" (instead of "quiet"); (4) boot without "initrd" line; (5) boot without "initrd" line and with "log_buf_len=16M ignore_loglevel initcall_debug" parameters (instead of "quiet"); (6) boot with "initrd" line and with line "log_buf_len=16M ignore_loglevel initcall_debug" parameters (instead of "quiet"). Unfortunately, no changes or any additional messages. I'm sorry if I'm doing something wrong. Please let me know if I should do something in a different way.
