Hardware errors in journalctl

Hi, I'm new to Arch Linux, so sorry if this is a stupid question.
Today when I booted my computer I saw some errors, so I checked journalctl and a lot of hardware errors and some other stuff came up.

sudo journalctl -p 3 -xb

Can anyone please tell me what should I do to fix these?

Re: Hardware errors in journalctl

Please wrap outputs in [ code ] [ /code ] tags without the spaces.

The only thing you really can and should do something about is the CPU hardware error, by updating your BIOS/UEFI and/or setting up your microcodes (you probably should do both).

The rest is errors with bluetooth which can simply be hardware quirks that aren't relevant to you, the drm issue is likely of mostly informational nature. the gdm issue is widely known but harmless message that should hopefully be silenced in the next release.

Re: Hardware errors in journalctl

Hey, so I updated my BIOS, and set up my microcode, following the Arch Wiki instructions:
- Installed intel-ucode package
- Updated GRUB with

grub-mkconfig -o /boot/grub/grub.cfg

- Checked /boot/grub/grub.cfg to see if /boot/intel-ucode.img was added after initrd, and it was
- Rebooted
After this I checked journalctl and the hardware errors are still there. I did

dmesg | grep microcode

to see if the microcode has been updated, and this is the output:

[    0.000000] microcode: microcode updated early to revision 0xca, date = 2019-10-03

Looks like the microcode did update, but the errors still show up.
