I see the same thing on an Ultra10...  I think I saw it first on a 
4.99.70 kernel (so it's been around for a while), and also see it 
with 5.0_BETA.  I've never managed to make time to investigate 
further, and thought it was maybe something messed up in my prom 
environment...  But it's good to know that it's not just my machine...
(Probably should get a PR filed on this... fixing it for 5.0 would be 
good too...)

Later...
