I've always noticed the resume=/dev/foo entry in /boot/grub/menu.lst, and that it corresponds to the swap partition, but I've never questioned its use.

title SUSE Linux Enterprise Server 11 SP2 - 3.0.13-0.27 (default)
    root (hd0,0)
    kernel /boot/vmlinuz-3.0.13-0.27-default root=/dev/sda1 insmod=qla4xxx resume=/dev/sda2 crashkernel=256M-:128M showopts
    initrd /boot/initrd-3.0.13-0.27-default

I was rebooting a server this morning and saw a boot message stating Starting manual resume from disk. Sounds like some sort of hibernate. So what exactly is resume? I'm trying to Google it, but all I'm seeing is resumes/CVs for Linux Admins :).

From the list of kernel parameters:

resume=     [SWSUSP]
        Specify the partition device for software suspend


SWSUSP  Software suspend (hibernation) is enabled.

So yes, it's used for hibernation.

Thanks for the info and link. Removing the resume= option and specifying the noresume option disables it. – Banjer Jun 11 '12 at 14:03
