Karmic boot delay - caused by "manual resume"?

Trying to upgrade to 9.10 from 9.04 on Toshiba Satellite laptop Core2Duo, dual boot with Windows Vista. 9.04 worked fine, 9.10 has problems booting, with several LONG delays. Initially tried updating with Update Manager, then tried a fresh install, reformatting swap and root partition, and results are basically identical. Seems to me that this manual resume is what is really slowing the whole thing down, notwithstanding a couple more delays elsewhere. I thought there were a few more threads around reporting a similar bug, but they didn't seem to address my problem (or I didn't understand them - relative newbie-level user I'm afraid). Here is what is happening:

and this, though this may be after the GUI has started, not sure
