Total noob here. I recently bought a couple of Giada Cubes and have been trying to get the suspend/ resume working. The fix in the wiki requires a grub update. I have updated the file but when I try and run the command
sudo update- grub
I get
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
I'm running live from a bootable thumbdrive (created using the wizard) with one of the nightly builds.
What does it mean and how do I get rid of it?
Thanks

I am using LIVE from one of the nightly builds.
My problem isn't necessarily suspend and resume. After the first resume I get the autoresume bug (hit the suspend and it will suspend for half a second and then resume). This is apparently due to a bug with Nvidia smb bus on certain machines.
The fix is to Disable Usbcore Autosuspend as follows (from the wiki)
Add a boot option to grub to disable the usbcore autosuspend. This bug exhibits itself as immediately waking after suspension.
Edit /etc/default/grub and add usbcore.autosuspend=-1 to GRUB_CMDLINE_LINUX_DEFAULT. Example:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash xbmc=autostart,noredir usbcore.autosuspend=-1"
Update grub:
sudo update-grub
as stated in the original post I can't run the grub update because of the following error
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?)
I unfortunately do not know how to make the gui call the aciptool.
Thanks
