Comment 21 for bug 462939

...add me to the list for this bug, as well. Dell Latitude D400 with built-in i855 graphics. Running Linux Mint 8 (Helena), which is essentially Ubuntu 9.10 / Karmic with a few bells & whistles tacked on.

I will try the kernel boot parameter when I get home tonight, and report back here if it doesn't seem to temporarily resolve the issue for me. I previously had Linux Mint 7 (Gloria) on this laptop, which is essentially Ubuntu 9.04 / Jaunty ...so, my issues are identical to those related in these comments... suspend/resume works fine under Jaunty (or Mint 7) and doesn't work under Karmic (or Mint 8).
