Looks like this is mostly figured out already but JFTR: As I said in the report there's nothing in the logs that I noticed, anything there is that I've missed should be in the linked logs.

Unsurprisingly given the above and the rest of the thread commenting out that check causes the affected tests to pass, I didn't check for any additional impacts.
