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.

Trace dump suggests that crash occurs while executing cpuidle module.
Try to boot with "intel_pstate=force" kernel parameter [1] to force
different CPU driver (if CPU supports it) and\or "cpuidle.off=1" to
disable cpuidle subsystem.
Also, it is a good practice to update BIOS\firmware of a server. [2] By
doing this you might solve a lot of issues with low-level next to
hardware problems, like these.
And installation of "intel-microcode" package should be a good idea.
