Just in case its not clear to a newbie, like me, this is (likely) a
duplicate of https://bugs.launchpad.net/bugs/566149 . If you're not
logged in, the only indication that this is a duplicate is in the box in
the uppper right hand corner of the page where it says "Duplicate of bug
#566149". I missed that.
Anyway, a fix has been proposed that fixes the problem for many people.
It should been in the kernel distribution soon, but is not yet present
in 2.6.32-22.
Probably the clearest indication of that bug is the following lines in
/var/log/messages (and in dmesg output) after a resume:
...

If you don't see the "disconnect" messages, then i suspect you have a different
bug.
