I'd like to see the one-liner fix, even if it turns out to just be a 
workaround that hides the issue and makes us go back to 2.6.27 behaviour. 
I'm about to release -rc4 today, we should be aggressive about 
regressions.

If somebody can test the "real fix" independently, that's obviously fine, 
but it's not an excuse for keeping a pending regression. If people end up 
being 100% sure they found the bug later, we can then re-enable it, but 
again - that has zero bearing on the fact that we should get rid of the 
regression asap.
