S4 is suspend to disk. It requires that you build a hibernation partition on the hard drive. Without it, S4 will not work (but you noticed that.). This is indicated by the value of hw.acpi.s4bios. To get S3 (suspend to RAM) to work, I'd suggest building a kernel without SMP or APIC. The messages you are reporting are indicative of problems figuring out the interrupt routing for multiple processors, but you have only a single CPU. Turning off APIC (and SMP it it's enabled) should return to the simpler interrupt delivery. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
