Hi Georgi I noticed that kernel logs you posted are between 62nd - 64th second > after kernel loading. Why is the boot process so slow? >
Due to a disabled SATA device in BIOS, the kernel tries to do an ERST and SRST and does this until 60s after boot. That's OK, it's been the same on Buster, too. > If you think that video driver can be an issue then you can try to > configure the system not to use framebuffer (if the system > doesn't use GUI). > Could you tell me how? Or a reference to it? In the meantime I re-configured grub to boot with the following parameters: debug rootwait earlyprintk=vga,keep earlycon pause_on_oops=5 panic=60 no_console_suspend The last two boots now show a crash in the console - even with firmware-amd-graphics and firmware-linux-nonfree installed.
