When I discovered suspend wasn't working after upgrading to lucid, I tried various things...and found that if I boot with old karmic kernel (2.6.31-21) suspend works.
But, that wasn't very satisfactory, so I kept looking....eventually found "PM: Device usb2 failed to suspend: error -16", and then I found this bug report. The workaround also seems to be working for me. -- cannot suspend usb devices on lucid https://bugs.launchpad.net/bugs/515109 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
