WTF -- this ended up in a bisect pointing to some PCMCIA patch! Justin:

  * does this happen with wireless-testing.git ?
  * Did you do the bisect on the entire kernel? What git tree are you
using to bisect?

Did you simply bring up the interface and then suspsend? Did you not
add a new interface in between this? ath5k's add_interace has:

        if (sc->vif) {
                ret = 0;
                goto end;
        }

But why does it just allow this to go through without complaining if
multiple vifs are not supported?

I see no updates to this since August. There are boat load of PCMCIA
changes recently, is bisect possible here?

This seems fixed.

Pavel already verified the PCMCIA-bigdiff since 2.6.35 does work, so it is
_not_ a PCMCIA issue.

no this is the current Linus tree(have not tried any other tree).
as for the unresolved regression, this just was filed a few days ago..

the bisect had to be between 2.6.34 and 2.6.32 due to pcmcia breaking 
after 2.6.34(there is a bug report for that, but got resolved)

the system is opensuse 11.2, I just simply start the machine boot up,
after nm connects I open a terminal then suspend in the terminal, upon 
wakeup this message appears.

yeah the first pcmcia bug I hit with this machine was back in may/june 
ended up doing a bisect for that(which was painful due to a slow 
machine)which ended up getting fixed.(never thought to check s2ram after 
that)

as for bluetooth the only issue I have with that is for my other 
machines which is hitting this: http://lkml.org/lkml/2010/9/1/61
(but have not had a chance to follow through due to doing the update 
broken web addresses in the kernel)

alright if this is with the latest wireless tree, then I can throw that 
in to verify that it is indeed fixed..
