@dkg I have created a test installer ISO with an updated driver. Would you give it a go, and see if this fixes the issue for you? If you have any issues, then please provide us with the dmesg output during/after installation? Thank you.
ISO with updated AACRAID driver: xcp-ng-8.3.0-20250606-aacraid.iso (sha256: 6bd06036ea7f4f3788bdeab4663dc4359917a314b2b6859a88cce9f31b5a5ae2).
