I did a quick skim of crashes marked as bad_magic (30% of the kernel crashes I saw for mickey):

And the next one is from the same client and looks the same.  So looks like some client is suspending every 1800 seconds and hitting the same crash over and over again.

Actually, that one client appears to be about 20% of all mickey kernel crashes and nearly all of the "bad magic" ones.

...but you'll be relieved to know that this sounds a lot like things I dug into in b/35555692 that seemed related to Broadcom Bluetooth.  :-P

Browser rate is high at 427(2-3x normal) CPM. Kernel is high at 138 CPM (10x normal).

Other numbers look fine.

Forked comment #1 (USB HID crash) to  bug #706899 

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available.

For more details visit https://www.chromium.org/issue-tracking/autotriage - Your friendly Sheriffbot

Moving to available.  No idea how important this is, but it's not something I'm spending time on at the moment.  Adding a few WiFi folks in case they are interested.
