On my thinkpad t61 running kernel 2.6.24-19 this behavior seems to be caused by suspending the laptop while in the docking station. If laptop is booted up and never docked, and no USB devices are plugged in this doesn't happen.
Steps to reproduce: Boot up Dock Suspend -- works fine Undock Wake it up At this point suspend never works again unless you reboot the laptop. The reason is the khubd is having some issues: it's waking up a lot, according to powertop, and lsusb hangs forever. My guess is that since suspend was done while t61 was docked in a station with USB keyboard and mouse, khubd is in a bad state, and after it's awaken it never recovers, thinking there are some non-existing USB devices that it keeps polling. At this point khubd prevents either suspend or hibernate from working. -- suspend only works once https://bugs.launchpad.net/bugs/206952 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
