  7 If you want to trick swsusp/S3 into working, you might want to try:
  8 
  9 * go with minimal config, turn off drivers like USB, AGP you don't
 10   really need
 11 
 12 * turn off APIC and preempt
 13 
 14 * use ext2. At least it has working fsck. [If something seems to go
 15   wrong, force fsck when you have a chance]
 16 
 17 * turn off modules
 18 
 19 * use vga text console, shut down X. [If you really want X, you might
 20   want to try vesafb later]
 21 
 22 * try running as few processes as possible, preferably go to single
 23   user mode.
 24 
 25 * due to video issues, swsusp should be easier to get working than
 26   S3. Try that first.
 27 
 28 When you make it work, try to find out what exactly was it that broke
 29 suspend, and preferably fix that.
