Hi Takashi-san,

Yes you are correct. I tested Chrome v5.4 on a CML Chromebook 'hatch' and
realize the SOF does no suffer from this issue because the 'sync write' fea=
ture
is enabled in hda_init. Soon I can reproduce the issue after turning it off=
. So I
think it's still worthy to have this fix in case we need to disable 'sync w=
rite'
someday.


Regards,
Brent
