Hm that would suck big time. At any rate, even if it was git
wireless-testing seems to have an issue right now. I'll confirm
shortly with Linus' own tree.

hpa's collection of 2.6 stable kernels, including extraversion stuff.

But the issue is *not* in linux-2.6-allstable, it is only present on
wireless-testing, and I went as far back as merge-2009-08-28. I was
using whatever tag was available prior to you moving to rc8, and that
worked.
