Bug detailed description:
--------------------------------------------------
System will hang when running etqw-demo on SKL.
Add i915.enbale_ppgtt=0, it still fails.
System often unable to load USB driver after reboot.
If enable the console command(console=tty0 coonsole=ttyS0,9600), the system can
not boot up, So I can not fetch the dmesg info.
Error information:
