SPAM: 13th gen intel instability

[ciara at dotylabs.pw]

Hey I've been using Proxmox 8.0.3, linux kernel 6.2.16-3-pve on a  13th 
Gen Intel i5-13600K with 128GB's of DDR4 ram.

I'm noticing routine issues while booting newer 6.2 kernels that prevent 
the os from fully loading the OS. This appears to be a new issue as 
within the last week and a half. The screen get's to the point of 
"/scripts/init-bottom" running and then the system just entirely hangs, 
and i have to hard cycle it.

One variable that lines up is that I also started noticing these issues 
after i upgraded to the pve 8 release. If i look at my reboot history i 
had 15 days of uptime within the month of july without issue, after july 
22 (when i installed pve 8) i have reboots nearly every single day.

I have tried downgrading to the kernel that i was using on pve 7 
"6.2.11-2-pve", that had been solid up to that point, however i'm still 
noticing issues during the boot process.

One other thing I noticed around the time the instability started is 
that I installed a intel-microcode update. However this is just a 
theory, the version being intel-microcode:amd64 3.20230512.1. I've tried 
uninstalling the package but the boot issue seems to still be occurring 
so perhaps this is just a red herring.

At this point i thought maybe my hardware went bad in some fashion, so i 
swapped out the ram kit, the issue occurred. I swapped out the 
motherboard, the issue occurred.  The only commonality is the cpu, and 
i've never seen a cpu go bad like this.

So far the only solution that has allowed me to reliably boot is 
disabling all power savings and turbo p state settings  and disabling a 
cstate settings within the bios, per a couple reddit threads that 
mention similar issues with the 12th and 13th gen cpu's. This solution 
is not ideal.. The next couple things i'm thinking of trying is just 
buying another cpu and seeing if this issue follows me. I've also tried 
booting to a ubuntu desktop usb that was also on the 6.2 kernel and i 
notice the same boot issues so it makes me think it's specifically a 6.2 
kernel bug, or my hardware is specifically broken for this linux 
release.. suddenly..

I've also tried booting to windows and not encountered system stability 
issues however i want to use proxmox..
