The problem will be ACPI related, not particular to swsusp or Suspend2, whi= ch =20 is why you're seeing it with both implementations. I would suggest that you= =20 contact the ACPI guys, and also look to see whether there is a bios update= =20 available and/or a DSDT override for your machine. The later will help if t= he=20 problem is with your particular machine's ACPI support, the former if it's = a=20 more general ACPI issue.
