Saw this on Sheriff-o-matic, filing bug to track work:

browser_tests failing on chromium.chromiumos/Linux ChromiumOS Tests (dbg)(1)

Builders failed on: 
- Linux ChromiumOS Tests (dbg)(1): 
  https://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20Tests%20%28dbg%29%281%29


First failing build: https://uberchromegw.corp.google.com/i/chromium.chromiumos/builders/Linux%20ChromiumOS%20Tests%20%28dbg%29%281%29/builds/23074

Failure snippet from log below. This looks like failing test:

https://cs.chromium.org/chromium/src/chrome/test/data/webui/settings/cr_settings_browsertest.js?type=cs&q=CrSettingsInternetPageTest&sq=package:chromium&l=910

though I don't see any changes made today or yesterday to that file.

Passing to stevenjb@ to see if he can help us route or identify cause as he has done work here recently.
