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.
But not all systems have iommu so check from dmesg that iommu is really
enabled.
