[Rafael David Tinoco <rafael.tinoco@xxxxxxxxxxxxx>]

I'm holding until I can get a feedback on the hot fixed kernel I have
provided into PPA. Marga said to Aditya to install extra kernel package
and we haven't heart if it worked or not.  After confirmation... if
positive I'll ask kernel team to SRU the fix, if negative I'll dig into
upstream code to cherry-pick the fix.

Thank you.

-Rafael
