According to Volanin's analysis, this seems to be something introduced upstream - likely in 2.6.22.8 or 2.6.22.9. I will also concur with the fact that after waiting 5-10 minutes one can always wake up the system - and sometimes pressing the power button wakes it before that.
Anyway, I have attached my dmesg files from the system. The first is the dmesg from before I went into suspend, and the second is from after I resumed from one of these "hung" suspends. Note that it took around 10 minutes to get the system to wake up. ** Attachment added: "dmesg" http://launchpadlibrarian.net/10228595/dmesg -- New in 2.6.22-13: System doesn't always wake 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
