This bug still persists with me using most recent 11.04 beta. I've noted that the problem only seems to occur when some amount of swap is in use when I resume - i.e. if I sleep soon after a reboot, when the memory usage is low, then my resumes are nice and snappy. However, after a few days of firefox-ing, where swap usage gets up to around 1 gig, then resumes are excruciating. I find it quickest to drop to a console and sudo swapoff -a - It seems to be faster to wait for the swap to de-allocate rather than wait for whatever is causing it to thrash to complete. I've checked my syslog, and I see a similar Call Trace to what others have posted. I'll attach the changelog, where you can see 3 successful resumes, and the 4th one (at Apr 14th 22:45:30) having the call trace. Interestingly, the syslog trace reports that I was only using ~ 31 megs of my 4 GB swap, but I'm certain when I disabled it, it was using at least 1.5 GB. Please let me know if there's anything else that I can report - this is definitely my #1 annoying Ubuntu bug.
Eesh - i tried to use ubuntu-bug to attach information, but could not for the life of me prevent it from creating a new bug. So, for more details about my system, see bug #761432.
