Public bug reported:
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.
