Kernel panic experienced with FreeBSD-10.0-CURRENT while running the chromium browser application. Had been using the operating system, and running the application "Chromium 27.0" for four hours. Accessed a page on Wordpress.com and experienced the kernel panic. Had been viewing many pages on Wordpress throughout four hour period prior to panic.

Responsible Changed From-To: freebsd-i386->freebsd-bugs reclassify.
Is this still reproducible on 10.1 or stable/10 for you?
For bugs matching the following conditions: - Status == In Progress - Assignee == "bugs@FreeBSD.org" - Last Modified Year <= 2017 Do - Set Status to "Open"
Now we have chromium 68 plus FreeBSD 10.0-CURRENT is no longer supported. I think it's time to close this PR.
