Julien, I've a similar issue on same machine, but I found that waiting 4 or 5 minutes the system wakes up in a proper way.
I filed separate bug #658307, due to collected acpi info after wake up. -- Black screen after resuming from suspend on Dell Inspiron M301Z https://bugs.launchpad.net/bugs/645115 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
