Image of  Call trace

Environment:
-------------------
Kernel: (drm-intel-next-queued)9d1cb9147dbe45f6e94dc796518ecf67cb64b359

         drm/i915: avoid unclaimed registers when capturing the error state

Description:
--------------------
When I test s4 in a loop , the machine will resume with call trace and the
network disconnect, and sometimes it will also hang at the same time. It may
happen at the 5 or 6 round of the loop ,or more like 24 round . I add the
picture of the call trace in the attachment.

Reproduce step:
----------------------
1.boot up machine 
2.echo 0 > /sys/class/rtc/rtc0/wakealarm ; 
  echo +10 > /sys/class/rtc/rtc0/wakealarm; 
3.echo disk > /sys/power/state
4.loop running step 2 and 3
