There are two problems being tracked for Browse on XO-1 now:

- #12866 rectangles instead of letters on the tab label, with an error
  reported in logs, and also causes the page rendering to stop,

- #12863 activity stops, with segmentation fault or illegal
  instruction, caused by SSE instruction while processing JavaScript,
  on google.com or youtube.com, was fixed on 14.1.0 by rebuilding
  webkitgtk3 without JIT,

Maybe you could try adding an exception handler for #12866, so that
the rest of the callbacks complete?

The just-in-time (JIT) compiler is possibly generating instructions
that the Geode processor cannot handle.  Maybe you could rebuild
webkitgtk or webkitgtk3 without JIT?

(When this was last tried in my lab, the problem had gone away on
google.com, so there was no conclusion ... perhaps it relates to the
phase of the moon or the number of digits in the day of the month!)

Is that crash practical to solve?  Might the Fedora 20 WebKit2 package
be backported to Fedora 18?

Have you tried with the workaround in #12860?

	sudo su
	echo 0 > /sys/class/net/eth0/lbs_mesh
	touch /etc/powerd/flags/inhibit-suspend
