I thought it could be that, too.

The attachment "dmesg-4" from the original email is with iommu parameters.
The attachment "dmesg-5" from the original email is with no iommu parameters.
Attaching here "dmesg-6" with the iommu explicitly set off like you said.

No difference, still broken. Although, with iommu off, there are less stack traces.

Could it be sysfs-related?

Kind regards,
Nicholas
