Once.

Please provide any additional information below. Attach a screen shot or
log if possible.

Below are some log snippets from the feedback report.

The syslog shows that a Chrome process crashed just before suspend [0], and then another chrome process crashed [1] on resume.
Unfortunately, I couldn't find any matching crash reports for this version and Client ID.
