kernel linux-hardened 5.13.17.hardened1-1 panicking on AMD cpu w

Hey guys, the kernel linux-hardened 5.13.17.hardened1-1 is panicking and i cannot check the reason, it runs, decrypts the root partition, shows "welcome to archlinux!" and continues checking services untill it crashes all of sudden.

the kernel linux-lts works fine on my amd ryzen 5. What can be the reason is it possible to solve the issue by downgrading (i'm on a fresh install on new hardware) ?

NOTE: i'm using LUKS on partition encryption scheme

Re: kernel linux-hardened 5.13.17.hardened1-1 panicking on AMD cpu w

I downgraded the kernel to 5.12.14-hardened1-1-hardened and it worked just fine !
i put linux linux-lts and -linux-hardened on ignore on /etc/pacman.conf and i'll wait about 3-4 months then i'll try to upgrade the hardened kernel again and see if the new releases don't panic again

please close this thread
thanks
