XCP-NG 8.3 freezes HP Proliant DL380 Gen 9

[Thunder-Cloud]

Installation of XCP-NG 8.3 works fine on our HP Proliant DL380 Gen 9, but then randomly after some days the host just freeze. I have reinstalled it several times.
Its booting to UEFI. Earlier it has been running XenServer 8.1 (booting to Bios) and it never had any problems.
I ran all the hardware diagnostics for weeks and no problems found.

Should I switch back to BIOS or is there any other things I could have missed?

Working on ours for years without issues. 8.2 and since release 8.3

Might be some hardware issue...

@manilx Is yours booting in BIOS or UEFI mode?

@Thunder-Cloud Have you checked to see that the BIOS / firmware is fully updated? Are there any crash logs in /var/crash?
