I am planning to upgrade from Buster to Bullseye, and trying to prepare 
for any problems.

The release notes say

I have no idea whether my old processor is a "CoffeeLake" or a "Skylake" 
or something else.  It is a pc that I bought in 2008, I think (and still 
working just fine).

/proc/cpuinfo says:
> vendor_id       : GenuineIntel
> cpu family      : 6
> model           : 23
> model name      : Intel(R) Core(TM)2 Duo CPU     E8400  @ 3.00GHz
Do I need to worry about those microcode bugs?

Thanks,
