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

The release notes say
The intel-microcode package currently in bullseye and buster-security (see DSA-4934-1 (https: //www.debian.org/security/2021/dsa-4934)) is known to contain two significant bugs. For some CoffeeLake CPUs this update may break network interfaces (https://github.com/intel/ Intel-Linux-Processor-Microcode-Data-Files/issues/56) that use firmware-iwlwifi, and for some Skylake R0/D0 CPUs on systems using a very outdated firmware/BIOS, the system may hang on boot (https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/
issues/31).

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,
