Hi Barteq, It appears that there may be some ACPI problems here with the IRQ setup - booting with acpi=noirq definitely shows a far quieter system with only a few hundred IRQs occurring over the 10 second sample periods. I suggest now fulling booting your system using "acpi=noirq" and see if this improves the powertop interrupt and wakeup events.
We may need to start looking at the ACPI DSTD - c.f. https://wiki.ubuntu.com/DebuggingACPI. In these cases one generally needs to dump the DSTD, decompile it and see if it's incorrect. Then fix it, recompile it and load it at boot time. Let me know what the fully booted system's activity looks like using powertop and the acpi=noirq boot options.
