I just checked 2.6.22-rc3 and the problem is not present which means something between rc2 and rc3 has fixed the problem. I hate it when problems (appear to) fix themselves as it usually means they're just hiding. I didn't see any patches between rc2 and rc3 that were likely to have fixed this (but doesn't mean there wasn't one). I'm wondering whether I should do a git bisect to see if I can find where it got fixed? Could you see if you can reproduce it on 2.6.22-rc2?
