I suspect we have some ugly (hard trackable) regression between
mainline and wireless-testing. It sounds impossible, but this seems to
affect Broadcom cards and looks like not related to ssb or b43.
Today I've compiled 2.6.38 and 2.6.39-rc6, both work GOOD.
I've compiled wireless-testing and it failed, BAD.
I've reverted all recent ssb patches from top and it still fails BAD.
What would be the easiest way to try bisecting? I can see
wireless-testing merges mainline quite often. Can I use some trick on
checkouted wireless-testing? Do I have to checkout mainline and merge
wireless-testing into it? Something even different?

git bisect can handle it...I've spent some quality time finding
bugs in ath9k with that lately...

The other thing to do is to see if branching wire-testing to 2.6.38 results in a
workable system.
What card fails? I've been busy with Realtek hardware lately and have not run
very much with Broadcom, but my 4311 worked earlier this week.

I've beed testing clean 2.6.38, so this should be GOOD. Hm, maybe this
is a good idea? Probably a few patches more to test, but should not be
more than 1 or 2 bisect steps.

This is really ugly. We are performing following scenario:
modprobe wl; connect; download sth small; rmmod wl;
modprobe b43; connect; try to download 2GB
With 2.6.38 and 2.6.39 usually whole 2GB gets downloaded, sometimes
card disconnects after 1GB.
With wireless-testing it fails after a minute or earlier. I've tried
reverting every ssb patch that is present in wireless-testing only
(including first patch: "serdes workaround").
Card is 14e4:4315 (BCM4312).

Sure it can ;) But what should I match as GOOD for first bisect?
wireless-testing merges mainline all the time. So there are
wireless-testing specific commits between John's merge of 2.6.39-rc5
and 2.6.39-rc6. I can not match Linus's 2.6.39-rc6 as GOOD, because I
won't test wireless-testing specific changes done earlier (these that
didn't go info mainline).
Maybe I should call GOOD a commit that wireless-testing is based on?
Which one would it be?
Or maybe I could rebase wireless-testing on mainline and then I could
use 2.6.39-rc6 as GOOD?
