Well, you have the most fun and non-descript disconnect cause of them all, the HOST_BROKER_GENERIC, with it's description of:
"PCoIP connection not established because of cancellation. This should not occur. Contact Teradici support."
It's possible you're on the right track with the hardware considering. I didn't see anything in that log that would tip me off personally, I was hoping the disconnect code would be useful or something else would stick out. Although, maybe someone else who has more insight into the logs will know more. Either way, definitely let us know if the hardware swap has any results.
