iommu: flood of ahci 0000:e6:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0055 address=0xa14a4000 flags=0x0070]

[Corentin Labbe]

Hello

I have a supermicro server which is flooded of kernel message:
ahci 0000:e6:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0055 address=0xa14a4000 flags=0x0070]

The server works perfectly anyway.
It happens with official ubuntu kernel vmlinuz-6.8.0-51-generic.
I tried also a custom 6.12.6, same problem.

I tried to update bios, no change.
I tried iommu=soft, no change.

I dont know what to do next.

Regards
