Following this thread and other form several weeks now i'm decided to write my experience.
Aliexpress box Topton N5105 (4 nics) with:
Corsair Vengeance SODIMM 16GB (2x8GB) DDR4 3200MHz CL22
NVME
Samsung Memorie MZ-V8V500 980 SSD (with upgrade firmware solved problem high temperature in proxmox)
Samsung HDD 2.5 1.75TB
Default bios stock is with c-state disabled.
Proxmox with:
3 vms: ( 1st Nic is for management of Proxmox )
- pfsense (2 Nics passthrough for WAN and LAN - enabling intel_iommu=on )
- Xigmanas on last Nic
- Homeassistant on last Nic
2 LxC
- Ubuntu 21.10 for Plex Server
- Ubuntu 20.05.5 for Omada TpLink Controller
I have it from jul 2022 ...
Homeassistant/pfsense/xigmanas reboot randomly from 1 to 10 days... even if vm is always on. The VM with Homeassistant is the most affected.
( 1-5 times i had total block of machine for pfsense and homeassistant - never for xigmanas)
Never problems for Containers
My tests:
I have tested all kernel available form stock to 6.1.10, and also edge versions.
Disabled turbo boost mode that set cpu from fixed 2.8ghz to fixed 2.0ghz.
So i have enabled cstate in bios and in grub with intel_idle.max_cstate=1 processor.max_cstate=1.
I have also installed microcode to last version ([Fri Feb 24 18:11:21 2023] microcode: microcode updated early to revision 0x24000023, date = 2022-02-19)
Tested also changing cpu type from host to kvm64 or qemu,
enabling/disabling qemu guest agent, with and without booling ram
Nothing Helped !!!
Now i'm test again with:
- microcode
- turbo boost mode on in bios
- cstate enabled in bios and grub
- all machine with cpu host type
- booling ram disabled
now i have insert "#" before blacklist microde in intel-microcode-blacklist.conf as suggested
@LiFE1688 and is online from 21 hours.
Very frustrating this situation !!!
