Hi Huisong, Jie
As you said some drivers don't do it right, and my concern is:
a) if we have a side effect from last minute changes from drivers,
b) if there are more drivers impacted but not recognized yet
That is why my proposal is to revert Jie's fix for this release, record
known issue, and merge it back early next release to give more time to
drivers adjust. What do you think?
