Hi, I've reported to archlinux's bugzilla, and finally found out the flag which
caused that issue, it's the `CONFIG_INTEL_IOMMU_DEFAULT_ON=y` flag, I think may
this is a kernel bug, more details at https://bugs.archlinux.org/task/55665
My standard kernel has the following:
CONFIG_INTEL_IOMMU=y
# CONFIG_INTEL_IOMMU_SVM is not set
# CONFIG_INTEL_IOMMU_DEFAULT_ON is not set
I will do some further testing to see if turning CONFIG_INTEL_IOMMU_DEFAULT_ON
also breaks my system.
