You have my sympathy.

It isn't just new ones that are struggling with this. I've had intermittent problems with it ever since updating to 2.7 (and the smart serial firmware updates that were pushed along with it.)

You don't mention if you've carefully examined your wiring for ground loops.

Todd, did you try the 77f.bit file? if you dont have severe noise issues that may solve the sserial error problem
(until 2.7.4 comes out though, any single error will be fatal))

Also Diederik: did you power cycle your machine after loading the new 77f.bit bitfile?

No, not yet. The machine (and myself) has been fairly busy lately, and since it mostly only seems to mess up when I hit the e-stop button. I haven't taken the time to mess with it.

Just tried it and I don't think it made any difference.
Here is what was spit out at the terminal.

Well if you get a sserial break error, you have a pretty severe noise issue (> 1.4V induced in DB25 cable for longer than 4 usecs)

Is it possible Estop causes a relay/contactor to open which doesn't have arc suppression?

The e-stop does open a contactor or two, and a few small relays. I could not tell you if they have arc suppression. They are in a separate electrical panel. All I know is I didn't see these problems before 2.7 (not that they weren't there) but the new tool planner is worth putting up with it.
