Hi guys,

I have a new pc with the following specs:

AMD Ryzen 5 5600GT Six Core CPU with Radeon™ Graphics (3.6GHz-4.6GHz/19MB CACHE/AM4)
GIGABYTE B550 GAMING X V2 (AM4, DDR4, PCIe 4.0)

2 x 1TB CORSAIR ELITE MP600 NVMe PCIe M.2 SSD (up to 7000 MB/R, 6200 MB/W)
2 x 240GB KINGSTON A400 2.5" SSD, SATA 6 Gb (500MB/R, 350MB/W)
8TB SEAGATE BARRACUDA SATA-III 3.5" HDD, 6GB/s, 5400RPM, 256MB CACHE
1 x 250gb USB Kingston SSD (Using sata to usb adapter)

Im new to Proxmox so not sure what to look for in logs but at the time of the reboots, I was copying data from the 8tb drive to the 6tb drive. For now Im not going to copy anymore and see if that stops the reboots (not sure why it would cause it to reboot). I have attached the 3 syslogs.

Syslog 1 - restart occurs at 17:03:31
Syslog 2 - restart occurs at 00:41:52
Syslog 3 - restart occurs at 05:23:01

I have tried the following in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet pci=assign-busses apicmaintimer idle=poll reboot=cold,hard"

and have also disabled c-states in the bios.

Im at a loss as to what is causing this so any help would be gratefully appreciated
