Yeah, it *seemed* innocent enough -- that's why I had to do a binary search on the 2.6.11-mm3 "series" file in order to find it as the culprit... > > (Recap of the problem in case this gets forwarded: Resume is almost > > instant without the apparently-guilty patch.

No. Reverting it from 2.6.12-rc2-mm1 (oops, I got the version number wrong in my previous mail -- and that should also be 2.6.12-rc2 not 2.6.11-rc2) speeds up resume to the original speed, but suspend is still ridiculously slow.

I kind of figured that from another LKML discussion but I wasn't 100% sure that's what I should do. -Barry K.
