It is easier to delete the _GTS/_BFS object.

And if we switch the EC to poll mode, the problem still exists on the latest
upstream kernel. In the latest upstream kernel the udelay is replaced by the
msleep when EC works in polling mode. And this issue is changed several times
back and forth. 
   It seems that the EC working mode will be changed by the following RFC
patch:
   >http://marc.info/?l=linux-acpi&m=123888812925650&w=2
      [RFC] [PATCH] ACPI: EC: Merge poll and interrupt modes

   In fact another solution is that Ec should be switched to the polling mode
in course of suspend/resume/shutdown. At the same time udelay should be used.
   Thanks.
