Hi
I'm sorry to report about regression in 5.10.37
with
CONFIG_IOMMU_IOVA=y CONFIG_IOMMU_API=y CONFIG_IOMMU_SUPPORT=y CONFIG_OF_IOMMU=y CONFIG_INTEL_IOMMU=y CONFIG_INTEL_IOMMU_SVM=y CONFIG_INTEL_IOMMU_DEFAULT_ON=y CONFIG_INTEL_IOMMU_FLOPPY_WA=y
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(
Should be fixed with 5.10.38. If not, please let us know.
thanks,
