Hi Prudhvi,
We might be chasing a different issue than just IOMMU being on. Do you have the same symptoms as Henning? You might be better off filing a new bug and we can debug your issues specifically.
Henning, are you still building your own kernels? Are things better on the recently released 5.19-rc1? Are you able to try a clean install of 22.04? Did everything work fine under 21.10?
Henning, there is a new kernel in -proposed, 5.15.0-36-generic, where IOMMU is disabled again by default, and it should clear up the IOMMU issues people are having. It should be released around the 20th, give or take a few days if any CVEs turn up.
Thanks,
Matthew
