By commenting the code segmenting out which makes it ignore the checksum
I could get apm to detect my battery and batterylife.
This is bad practice and I would like not to do it this way but it makes it 
work.

Is it possible that my laptop doesn't live up to the ACPI specs or something?

Here is a link to the acpidump archive file:

https://cloud.prozum.dk/public.php?service=files&t=78661b263f4932df157c13a94c5209e7

On Debian I also got the error "Wrong checksum for XDST",
I can still read the battery on Debian which I can't on OpenBSD.

I also found the "return NULL" that I am hitting in 
sys/dev/acpi.c:acpi_maptable()
It is the 4th NULL which is in the codeblock:

if (acpi_checksum(hdr, len)) {
acpi_unmap(&handle);
return NULL;
}

It is definitely the checksum that something is wrong with,
I don't know how to fix it though.

I tested with the snapshot from January 7. Now the xhci port works fine
after resume. Thanks!
