I'm sorry to report about regression in 5.10.37



and iommu=on in grub.cfg

All my dell r340 and all lenovo servers won't boot any more. Just black 
screen at once.

with intel_iommu=on iommu=pt DELL R240 and Lenovo SR350 cat boot

Older Lenovo cannot boot even with "intel_iommu=on iommu=pt" only with 
iommu=off in grub

With iommu=off in grub all servers are booting well

With 5.4.36 do not have this problem

tested last 4 days with 10+ different servers(
