Symptom:
With an SD card inserted, the machine will not suspend. On a reboot, with SD card inserted, suspend works once. After that, the computer will not suspend, or shutdown, even if I physically remove the SD card, I still have to manually hard boot the machine. I have also tried using software eject in nautilus, which does not help the issue.
This is reproducible every single time using the above scenario.
When the issue occurs, the machine looks as if it is going to suspend, in that the screen goes black as expected, but it just hangs at the cursor and does nothing. Usually if I press a key, the login screen comes back, but if I shutdown, I cannot get the login screen to reappear. Opening a terminal via alt+F2 and restarting gnome-session does not work.
If the SD card is not inserted upon reboot, the machine suspends and shuts down just fine, every single time.
Steps:
1. With SD card inserted, Power on machine
2. Log in
3. Wait for wireless to connect/services to start
4. Click user login menu, select suspend
5. After machine suspends, wake it back up
6. Log back in
7. Suspend machine again
Result: After step 7, the screen goes black, but the machine does not appear to suspend (light on the front of the system does not blink. Pressing a key usually brings the login screen back. If you attempt to suspend again, even if you remove the SD card, it will not suspend. If step 7 is replaced with Shutdown/Restart machine, the machine will not shutdown or restart, and only a black screen with a blinking cursor is shown.
Notes:
After using tail to follow /var/log/messages and /var/log/syslog it appears that there is a GPF occurring, and some message about the kernel.
Config:
Dell Mini 9, 1GB ram, 8GB SSD, 16GB SDHC 6X, Ubuntu 8.10 (installed updates)
I don't really know enough about Linux to debug these. Does anyone have a solution/fix for this, or have any advice on how I can proceed to try and debug this?
Thanks much,
