System Environment:
--------------------------
Regression:
good commit:
cd52471999ef08bca35568525c1d85d883ffedb6
Platform: BDW-Y
Kernel:
--------------------------
-nightly latest 9438dec1c7538fdd3b356a59ca929632fcb57132
Bug detailed description:
-----------------------------
I have tried S3 on BDW-Y with the night-latest kernel. And the first S3 can
work normally.The second and third times, it has write error: Resource
temporarily unavailable.
If any more ,it will call trace and can’t S3 any more.
Since the machine doesn't have any serial port or built-in network card, we
can't catch the dmesg. And the call trace message seen as the attached picture.
Steps:
---------------------------
echo mem>/sys/power/state for several times.</pre>
