Daniel,

Thanks very much for the step-by-step guide.   I haven't tried the
nolapic_timer method yet but the intel_idle.max_cstate=0 certainly
fixed the issue on my Samsung N220 Plus.

Thanks again!

>  Recently upgraded from 10.04LTS to 10.10 Beta on a Samsung N150 NetBook.  Since update, my netbook does not resume from suspend state after lid is opened.  Power, disk, and wireless activity lights turn on, but screen does not wake up.  I cannot ssh into the netbook from a remote host so I do not think that the network is resuming even though the wireless light indicates that the card is on.  I have to power off/on the netbook once it is hung in this state.
