XCP-ng 8.3 No Longer Compatible with Older Adaptec RAID Card?
-
I have a system with an older Adaptec ASR-71605 RAID card that has been working fine with XCP-ng 8.2.1. Otherwise the system is Intel 14th gen consumer grade hardware. When I attempt to upgrade to XCP-ng 8.3 by running the downloaded ISO from a bootable USB drive, the installation freezes during the step to "backup the old installation". After several tries and a few hours of waiting, I gave up on the normal upgrades. Sorry, I didn't save the log, but there was a lot of AACRAID timeout errors like those shown in this photo.
Then I tried to upgrade to 8.3 using the alternate kernel, and this works. The server will be up and running for some hours, or a few days, but eventually the VMs and hypervisor seem to lock up (ALL storage is connected to RAID through the Adaptec card). The photo above is the result of this issue. Everything seems to lose, or at least have extremely slow access to the disks.
I did not try running the server with the alternate kernel, just installing with it. I don't know if the alternate kernel would be stable with the Adaptec card in the long term.
For now I left the system at 8.2.1. I'm sure I can replace the RAID card with a newer supported card, which I may do, but I'm wondering if there's a simple and known fix for the older cards that worked on 8.2.1 but eventually stop working on 8.3?

Mentioning also @Team-Hypervisor-Kernel who now manages the drivers.
Maybe it's related to https://github.com/xcp-ng-rpms/microsemi-aacraid/issues/2#issuecomment-3837183087
It looks like the switch to the vendor driver instead of the kernel built-in for 8.3 (initiated by XenServer, and that we followed at the time as it was probably made in order to support newer cards) was not without drawbacks.
