Thank you for the fantastic information in this thread! A life saver (literally for my hardware 
).
I had the exact same problems on my HP EliteDesk 800 G5 Mini PC (i5 9500) with Proxmox 8.2.7). Reboots after a couple of hours. Sometimes paired with the BIOS error 90D from HP stating that the CPU ran too hot (but the fans never spun up).
I can confirm (7d+ uptime vs reboots every few hours) that both solution work for me:
- renaming /lib/firmware/i915/kbl_dmc_ver1_04.bin as a quick fix (needs to be done again after some updates)
- Adding kernel parameters as pointed out by Winterd85 and others (thank you!). This solution is less hacky and more stable for me.
