I saw several acpi power state errors as the system suspended. On resume, the system came back up, but the display remained off (no backlight). I was able to type 'shutdown -r now' and do a clean reboot. Of course, the number of differences between single and multi-user are substantial, but this eliminates a LOT of things. I then tried coming up to multi-user, but not starting X (Gnome). Again, it suspended and resumed with no display. My network came up and I sshed into the system from my phone. Then I got an interrupt from my greyhounds. Time to brush their teeth. I was away from the laptop for about 10 minutes. When I came back, it was dead. My ssh session was hung and I could no longer ping it. :-( Weird. It's getting really close, but not quite. I suspect that the video ties into it in some way. I also mount a couple of FUSE NTFS partitions when I start X (Gnome auto-mounts them). When I suspend in Gnome, the network never comes back up and the power LED pulses just like it does while suspended, so it really does not finish the resume. I think I can now eliminate the wireless (iwn), at least. Thanks for the suggestions! -- R. Kevin Oberman, Network Engineer E-mail: kob6558@gmail.com
