Since nobody gave you an actual response yet, you can see Linux-compatible hardware here: https://linux-hardware.org/

Note: The list is much larger than Windows, for everything from CPUs to peripherals

I've always been able to read that my kernel is included in an update.

Are you updating throught he command line or some visual front?

And 1200 packages? I run arch (btw) and only get ~250 a week.

Looking for a more stable distro could be a good idea. Some distros are pretty much only PoC, or too niche to have a good support, or the beta channel of another, better supported distro.

I've yet to run into a CPU that doesn’t work with 11
Every AMD processor from the Ryzen 1000-series and older. I'm not sure where the line is with Intel processors, but requiring TPM excludes a lot of otherwise useful hardware.

I've always found the Tpm complaints a little suspicious. The same people who go on and on about how much they worry about security and privacy and how MS doesn't care, suddenly just don't give a shit in these cases. I assume they mostly just want to shit on stuff.

It's a good to push to make it standard and hardware manufacturers wont without a good old shove.
