Upgrade to linux 5.4 gave some issues

Hi all,

Last night, I ran pacman -Syu, as I regularly do, but, for the first time in all my years of using Arch, it left my machine slightly borked, and wasn't able to boot into X. Logging into an alternative TTY showed that nearly no kernel modules where loaded (i had USB, ext4, hid and some minor bits and bobs), things like sound, networking were all gone. Now, it seemed like it was the upgrade from linux 5.3 to linux 5.4 that cause most of this, as downgrading to the previously installed kernel fixed, almost everything.  Sound, networking and friends where back. But my nvidia drivers where still gone.

So, two questions

a) is there a manual step I need to apply going from 5.3 to 5.4 to keep all my kernel modules getting loaded?

b) do you recon the nvidia issue is related?

All the best,
Daniel

Check the journal for the 5.4 boot,  was the kernel loaded actually 5.4.Y or 5.3.Y indicating the kernel had not been updated along with the package.

Re: Upgrade to linux 5.4 gave some issues

Hi again.

Thanks for the suggestion. I've validated that it is loading 5.4.Y. I suspect that the problem is actually related to an Nvidia upgrade that happened as part of the same system upgrade. Rolling back both the kernel and the nvidia driver to the previously installed versions, put my computer back to a fully functioning state.

I got a ton of work on atm, that requires a working machine, so, I'll leave it for the weekend.
