We (myself and Corentin Chary) tried to stop that patch once I'd noticed the
problem – I updated the patch, tested (all was fine with the rt2860 card),
upgraded from -rc3 to -rc4, installed an Intel 3945 card, tested, sent the
patch, restored the rt2860 card to its proper place, happened to toggle
wireless, got a panic due to having failed to remember to actually apply the
patch to -rc4... at this point, I rechecked with the Intel card (this time
with a patched kernel), saw a failure (stuck process – hmm, should rfkill be
re-entrant?), reported it, went digging into rt2860sta and produced, tested
and sent the replacement patch, then tried to stop the broken patch from
going upstream.

A reversion patch has been sent by Corentin (shortly after you reported this,
though the commit message says that he's reacted to its being in rc5) and,
earlier today, I directly requested that it be reverted; so hopefully, one
way or another, -rc6 will be fine for Atheros users and anybody else affected
by this, much as -rc5 is for rt2860 users.

Oh well. So much for Linus's "no new regressions". ;-}
