I don't know if this will help nailing the bug, but I have found a way of reviving my MacBook when suspend (with the 2.6.22-14 kernel) fails. It does not work every time though. When resume fails (no backlight on the screen), start tapping the power-button. Sometimes tapping the spacebar and the return key helps too. Most of the time the backlight will light up and you will be presented a login screen. However, when entering your password, you will notice keypresses are registered twice about 80% of the time (once for pressing the key down and once for up). Struggle with this until you're able to enter your password correctly and your laptop should be resumed now. (The double keypress issue disappears after login.)
Note: in some cases, your system will not be usable: it will freeze after each keypress. (I'm not into kernel development, but I think the kernel only schedules tasks or wakes up when an interrupt happens.) This is scary (for me) but it will enable you to reboot your system: just reboot and keep tapping keys (spacebar, once every second should do) until everything is cleanly (?) shut down. -- New in 2.6.22-13: system takes a LONG time to resume from suspend https://bugs.launchpad.net/bugs/151016 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
