Something else to worry about is bisections. People seeing an unrelated 
issue with .27 after release may well be asked to do a bisection and 
could then run into the issue even if it is fixed before the release.

Guess we'll need to wait and see what the root cause is to know if that's 
a real concern or not.

Extra datapoint. As far as I've seen this problem has not yet been 
reported by any people running Debian. This could point to X.Org as 
Debian currently has 7.3 while I think the reports so far have been with 
7.4.

I have been running .27-rc kernels myself on a HP 2510p laptop running 
Debian/lenny which does have the "bad" NIC (ICH9), but it's still working 
for me. I do have some vague resume from suspend problems, but for now 
I'm assuming those are unrelated.
I have been running the kernels both with and without PAT enabled.
