The problem as i see it is the kind of answer Johannes gave when the bug 
was bisected to by Jeff Chua two days ago:

  Subject: wpa2 hangs v2.6.32-rc5-402-gb6727b1. Revert
           7d930bc33653d5592dc386a76a38f39c2e962344 fixed it.

Unhelpful, defensive, in denial.

Plus that you tried to berate Dmitry in this particular thread about the 
revert was pretty bad form too IMO.

_Anyone_ who went through the unnecessary, avoidable cost of having to 
do a bisection of a 3 days old commit merged at around -rc5 time is in 
his full rights to ask for a revert, straight from Linus if he thinks 
so. No ifs and when about it.

So IMO you are showing the wrong kind of attitude for a post-rc5 
regression, by a _wide_ margin. The right kind of attitude would be:

  "Oops, my bad - thanks. I've queued up a revert."

or:

  "Oops, my bad - thanks. Does the attached patch fix it?
   If not we'll revert it."

Furthermore, your 'hey, nothing happened, we fixed it after all' 
argument is just a forewarning that you learned nothing and such 
avoidable incidents could repeat in the future.
