Thanks for the report, which I just found. It looks like - the extension_pref_value_map issue is tracked in bug 772638 . - the network_metrics_provider is tracked in bug 636015. I'll arbitrarily narrow this issue down the the chromeos one: https://cs.chromium.org/chromium/src/components/storage_monitor/storage_monitor_chromeos.cc?l=163 CCing folks who touched this file recently and hence might be familiar with it (pdfium bugs should be filed against pdfium, and I don't want to bother right now)

I've run across this and seen it a number of times in logs (in 67+). Since I'm looking at mounting issues, I'll take a stab.

I've taken a look and this essentially happens when there's an unmount failure. Then StorageMonitorCros will retain the mount point and the next time you insert a disk with the same mount point, it'll be ignored by StorageMonitorCros. The only use of StorageMonitorCros for disks is the system.storage.onAttached API, which doesn't appear to be widely used.

Can you remove the NOTREACHED() please? NOTREACHED() is a crash in debug..

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/2d9a675ef69c1a03c235e62ee1a4c9bf95144f15 commit 2d9a675ef69c1a03c235e62ee1a4c9bf95144f15 Author: Michael Spang <spang@chromium.org> Date: Tue Oct 23 21:52:13 2018 Remove NOTREACHED in StorageMonitorCros::OnMountEvent Logging in with a USB drive connected is enough to hit this NOTREACHED().
