I tried a mouse, usb stick and cdrom. The cdrom gets power from the port so I can open the tray but it does not attach. Fix: After a reboot the xhci port works again dmesg from a kernel compiled with XHCI_DEBUG including a suspend-resume cycle: Apparently Renesas HC need to be completely reconfigure upon resume. Linux have a quirk for such piece of hardware. I'll try to bake a diff unless someone... ok I can dream :) I just committed a workaround for this issue as I couldn't find any documentation for a proper fix. Anyway I can no longer reproduce the problem. Let me know if it still does not work on your machine. Regards, Martin I tested with the snapshot from January 7. Now the xhci port works fine after resume. Thanks! Remi

Can you get an acpidump from FreeBSD?
so it can't be a problem with the laptop.
Yes it can, but these other OS might be ignoring it.
UKC disable mpbios
53 mpbios0 disabled
why?

FreeBSD is currently not installed on the laptop but would a Debian
acpidump be good enough? I can install FreeBSD if it's required.
Might be. I'm not really familliar with the Linux acpidump tool, but
if it dumps all the tables in raw format, it might be useful.
The mailing lists will strip attachments, so best if you put it on a
webserver somewhere from where we can download it.
It looks like you may be able to do this with linux's acpidump:
acpidump acpidump.out
- this should produce a text file
acpixtract -a acpidump.out
- this should convert it into a number of .dat files which are what
might be useful to us (you should also be able to run iasl -d file
to disassemble them); tar up the .dat files and put them online
somewhere.
Anyway, what we need to figure out is why mapping the RSDT table
fails. 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=filest=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.

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?
