Description Weilong Chen 2018-01-23 07:47:14 UTC 
Description of problem:
Second kernel hang with intel_iommu=on

We can reproduce the problem by the following steps:
1.start the kernel with intel_iommu=on
2.ifconfig eth6 up;ifconfig eth8 up.(eth6 is Intel Corporation 82599ES 10-Gigabit and eth8 is Broadcom Limited NetXtreme BCM5719 Gigabit Ethernet)
3. echo c > /proc/sysrq-trigger
