Upgraded from 10.04 to 10.10 removed hibernate option for me and introduced the problem where by after entering standby (being indicated by blinking amber LED on my laptop) I cannot resume my session. Instead I get a crash and system reboots (crash comes instantly on trying to resume).

Tried clean install to eliminate possibility of an upgrade issue but its still persistent. All latest updates installed.

Tried looking for an answer to this but still no joy. Laptop is Sony VGN-FW41E.

If the solution below does not work for you, try this one:

  • Edit the file /etc/default/grub (as root)
  • Change the line with:

    GRUB_CMDLINE_LINUX=""
    

    to:

    GRUB_CMDLINE_LINUX="acpi_sleep=nonvs"
    
  • run update-grub (as root)

Worked for me... Hope this can help you!

I've solved a similar issue (reboot on resume) with a Sony Vaio VGN-FW51ZF by changing the last line of the file /etc/acpi/sleep.sh from pm-suspend to pm-suspend --quirk-radeon-off (guess it was a problem related with ATI proprietary drivers).

Hope this can help you!
