Fixing Crash On Sleep Resume In Ubuntu 11.04 Lenovo S10-3t

I found that the fix in comment 25 here.  To do this, I added this text to /etc/default/grub, under the following add the "nohpet" part:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nohpet".

I then did sudo update-grub to publish the changes. From then, resume works, both from a suspend via the shutdown menu, and from closing and opening the lid.

  2. Sorry for the typo. I corrected it in the post. The correct flag is nohpet.

  3. The nohpet option worked for me for a while, but then the problem came back again. I had found in another post that intel_idle.max_cstate=0 also worked. For me the second option worked intermittently, but both options together are working consistently.

  4. That worked very well for me!
    Thanks for the hint.
