重启crash报错截图

Description of problem:
龙蜥7.9 系统，内核4.19.91-27.1，物理机硬件使用E810网卡，使用SR-IOV功能时，在grub启动参数中开启intel_iommu时，系统启动后会不停重启，截图报错“kernel BUG at derivers/iommu/iintel-iommu.c:1228!”，其他操作系统开启intel_iommu参数没有问题。
grubby --args="intel_iommu=on" --update-kernel DEFAULT

Version-Release number of selected component (if applicable):
龙蜥7.9 系统，内核4.19.91-27.1

How reproducible:
物理机硬件使用E810网卡，在grub启动参数中开启intel_iommu时，系统启动后会不停重启，截图报错“kernel BUG at derivers/iommu/iintel-iommu.c:1228!”
grubby --args="intel_iommu=on" --update-kernel DEFAULT

Steps to Reproduce:
1.龙蜥7.9 系统，内核4.19.91-27.1
2.物理机硬件使用E810网卡
3.在grub启动参数中开启intel_iommu时，grubby --args="intel_iommu=on" --update-kernel DEFAULT
4.系统启动后会不停crash重启，截图报错“kernel BUG at derivers/iommu/iintel-iommu.c:1228!”

Actual results:
系统启动后会不停crash重启，截图报错“kernel BUG at derivers/iommu/iintel-iommu.c:1228!”

Expected results:
系统应该正常启动，不应该crash重启

此问题是内核导致还是驱动呢
