Thomas,
I've been seeing these messages more and more lately.
When I start a kernel build for eg, it seems to spew regularly..

According to git, you ratelimited this back in 2007 with the message
"until we found the root cause of that problem."

Is this an old problem that has returned ?

Maybe interesting note: Both machines I see this on regularly are Atom cpus,
and it's always '08'.
