Another behavior- sometimes the computer wakes up and then immediately goes back to sleep. After that happens, the next time it wakes up it seems to have an even chance of crashing or of resuming normally. Attaching a new syslog which demonstrates both problems. The crash at Nov 1 17:00 is still in this log; but further on, at around Nov 1 18:59 the computer is woken up (lid opened) and then immediately goes back to sleep without prompting. The next wakeup attempt is successful some hours later, at Nov 1 20:38.
Here's the relevant excerpt from syslog: ...

I want to stress that the computer was sleeping between 18:59 and 20:38, and that the wakeup at 20:38 was successful. is this too weird / hardware specific to file a bug report? ** Attachment added: "updated syslog with additional events" http://launchpadlibrarian.net/19212909/syslog -- thinkpad x200 hangs, reboots on resuming from suspend to ram https://bugs.launchpad.net/bugs/292422 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
