You know what, I wonder if you're running into the CUR_TEMP_RANGE_SEL? I.e., sometimes the CPU chooses to report on a range from 0-225C and sometimes -49C-206C. I think someone else's 2990WX did the same thing. I guess that patch never landed? 102=C2=B0C - 49=C2=B0C is the ver= y reasonable 53=C2=B0C. Yeah, sigh, it never landed: https://reviews.freebsd.org/D16855 Ok I'll go ahead and commit that too.
