Hi, thank you for the answer.

I have found a very saddening way around the problem:
1. Installed stock Debian kernel, worked
2. Looked through the Debian patches if there's something obvious. No.
3. Took the Debian configuration, worked.
4. Changed the config "back" to what I like. Doing stepwise, it always
5. I now have a working kernel configuration.
I'm a bit frustrated because I did not 100% figure out what went wrong.
In the ACPI stuff I could see no difference between the working config
and my broken config. Perhaps something I don't know has side effects.
