Comment 1 by michaelbai@chromium.org, Mar 10 2017

Owner: roc...@chromium.org
rockot@ It seemed you are owner of related code, could you take a look?

Comment 2 by roc...@chromium.org, Mar 10 2017 

I can't really do anything this this. Do we have actual crash reports?

There have been similar crashes in the past ( issue 665869  is one example) that were due to hardware errata, and our unfortunate but successful solution was to perturb the binary slightly in order to dodge the bug.

It seems likely that this is a similar scenario, as this code path is hit in extremely high frequency on all platforms and we aren't seeing any noticeable volume of crash reports.

Comment 3 by michaelbai@chromium.org, Mar 10 2017 

Is your fix in 56.0.2924.87 ?

Comment 4 by torne@chromium.org, Mar 10 2017 

That was suspected to be a hardware errata on one specific Tegra CPU. It's unlikely it will have any impact on a crash happening on a Samsung device.

Comment 5 by roc...@chromium.org, Mar 10 2017 

That fix is in M56 but probably not relevant. I'm not saying it's the same
bug, just raising the likely possibility of a hardware problem.

Comment 6 by roc...@chromium.org, May 29 2017

Mergedinto: 703421
Status: Duplicate (was: Untriaged)
Looks like a dupe of 703421 - i.e. we have a deadlock caused by an sendmsg blocking on what should be a non-blocking socket fd, while holding a lock some other thread needs to acquire.
