Hi Joseph,

Unfortunately that kernel patch alone did not resolve the problem.
This bug seems a bit stale, waiting for developer/analysis cycles.

cheers,
Mauricio

Indira,  thank you.

Wendy,

reassigning back to you for further analysis,
as only Paul's patch was not sufficient to fix this problem on Ubuntu.

Hi Indira,

Can you verify the Mauricio's kernel with your test?

@Joseph,

Yes, exactly.

If you'd recommend to submit it earlier, since already accepted
upstream, I can do that --

We know this patch fixes problems with similar symptoms on other distros
/ duplicates, but since this involves a SRU request to LTS, in an area
such as RCU, I'm clearly following the SRU requirement of testing first.
:- )

cheers,
Mauricio
