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?

If you happen to have some hacking skills you could try to >> figure out which "return NULL" in sys/dev/acpi.c:acpi_maptable() >> you're hitting on that laptop. 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.

Now the xhci port works fine after resume. Thanks! Remi
