Since we're likely to be moving to 3.0 for the next release, it might be good to try to get this fixed upstream.

Oh. This is the same issue Andy mentioned in a thread a week ago.
And even more humorously is the fact that I'm forgetful enough that I had *also* hit this and found that the fix is reverting 7e6502d577106fb5b202bbaac64c5f1b065e6daa
So is there a fix in the works or should I request Linus just revert that?
Or maybe I'll just go ahead and put a reminder in my calendar for next week when I hit it again and have forgotten I already know the fix?
thanks -john

Other then the discussion on linux-usb that found it and mentioned it should be reverted, i haven't seen a direct revert request yet to linus....

Yea, I just sent mail to the patch author to clarify if there is a fix pending or if it should be reverted. Hopefully we can get this sorted quickly, apparently the issue has been around since -rc1.
Thanks for the pointer to the fix as well! -john
