I compared the /proc/acpi/wakup of both kernels - they equal. So that's
not the problem

The problem is, that Arch uses almost everything as modules. I have a

compiled, as I don't want to have modules inside my initrd.

Anyway, I'll try it out.

Thanks for your config! I tried it - just made a few adjustements
(statically compiled dm-crypt and crypto modules). Still the same problem..
