I did that bisecting work, and narrowed down the failure to a couple of days between 5/1/2011 and 5/3/2011. There was a single large mod that makes major CPU handling changes at that time.

Look for subject "Re: Confidence: Chopping between 5.2 and 6.0.1" around March 2013 in the MacPPC NetBSD mail list.

There is a fair amount of commentary in the above thread.

There is also a more recent thread with a short test case that simply repeatedly asks for the current time - that fails.

Look for: "Problems with registers save/restore on context switch?" in the email threads in Dec 2013.
