I will retest both patches (as I already mailed you privately yesterday),
but not today. The improvement with the combination was real, but I'm not
sure which patch is the reason. I think the second, but I need to verify.
I've done another 30 boots or so today, mainly in the "akpm" merge, and
I've found new patterns that will help me nail down the regression. But
ATM I can't see straight anymore, so it will have to wait until tomorrow.
I'd suggest to delay merging any patches for now. There are still too many
open ends.
Cheers,
FJP
