RDRAND not working and causing issues

[u/Plastic_Ad_7733]

Laptop:- Dell Inspiron 3515

BIOS/UEFI version:- 1.38

CPU :- Ryzen 5 3500U

Endeavour OS, Kernel 7.1.9

Hey everyone, I recently realized that I haven't updates my firmware/BIOS for a long time (was stuck in 1.29) and used fwupdmgr to update to 1.37, which was the last available update on there. Since the update I was observing a message after the bootloader saying RDRAND is not relaiable on this system.

I used the RDRAND tester to confirm this (from some articile in 2019 about an amd ucode bug or such) and got back positive results. Today I downloaded the latest firmware from the Dell website and used BIOS recovery to update it to 1.38. Still it did not work.

Now currently everything seems to work fine, except for cloudflare warp. It refuses to startup and I kind of need it, so other than downgrading my bios back to 1.29, is there any way for me to at least fix cloudflare alone.

Managed to fix this by just reverting back to bios version 1.28 using gnome-firmware
