[SOLVED] Disk I/O errors after suspend

I have a Lenovo ThinkPad Z16 Gen 1, model 21D4002GGE.

When resuming from suspend, the system freezes up and I cannot start new programs.
Any command will trigger an I/O error.
I suspect that, when resuming from suspend, the disk is not properly re-mounted.
What could be the reason for that?

Solution
Fixed with iommu=pt as per this thread.

Update
After an EFI update via fwupdmgr the suspend now also works without iommu=pt.
