A Page Fault could be a memory problem, but first thing to do is uninstall all of these:
tc.tctechnologies.driver.Saffire 4.3.0 41017
Once you have removed them following the developer's uninstall instructions or using their uninstaller, test to see if you still get panics.
If the panics don't happen, start reinstalling them one-at-a-time until you get panics again. That is the problem driver. Check the developer's web site for updates or solutions.
If the panics do not go away after uninstalling all of those things, then it could be a RAM problem. You can test that with the Apple Diagnostics or http://www.kelleycomputing.net/rember/
