This series of patches fixes several bugs found by putting a mutex inside e1000_acquire_swfw_flag, and then the patch from Thomas actually adds this mutex to help find any further bugs.
Like Jesse Barnes said, "totally up to you (obviously) whether we stuff this into 2.6.27 or hold on it until 2.6.28."
Linus, since you mentioned this exact same issue that Thomas (and Dave Airlie) spotted I figured I should just send these. Testing will continue over the next couple of days and I'll let you know immediately if we find something.
The patches are pretty straight forward and each one fixed a separate bug we found using the mutex patch. It is possible that these fix the actual corruption issue but we haven't verified that yet.
