I think I've figured out the cause for those faults, and posted a fix
here:
https://lore.kernel.org/xen-devel/20250124120112.56678-1-roger.pau@citrix.com/
Fix is patch 5/5, but you likely want to take them all to avoid
context conflicts.
Can you give it a try and see if it fixes the fault messages, plus
your issues with the disk devices?
Regards, Roger.
