ACPI on CoreBoot ThinkPad

Sat Dec 29 21:19:26 UTC 2018

Hi list,

I am trying to have reliable suspend and resume on my laptop after
flashing CoreBoot and SeaBIOS on ThinkPad T430s.
Problem is that system will shutdown because it thinks that temperature
is too high:
> acpi_tz0: WARNING - current temperature (128.1C) exceeds safe limits
Laptop was in suspend less than a minute and it is not too hot on touch.

Not sure if relevant, but I noticed that acpidump from base doesn't
work:

Another try with acpidump from ports:

> /usr/local/bin/iasl dsdt.dat

So, at least I can use that DSDT:
  cp dsdt.dat /boot/dsdt.aml
  /boot/loader.conf:
  acpi_dsdt_load="YES"
  acpi_dsdt_name="/boot/dsdt.aml"

Full "dmesg.boot" file is attached.
But now with DSDT unmodifed, my system lost sysctl dev.cpu:
sysctl: unknown oid 'dev.cpu'

I have also tried to boot Linux (which doesn't have problems with resume
after suspend) and dumped ACPI tables but that was not successfull
(IIRC, problem was that FreeBSD was unable to parse DSDT from Linux)

I am using FreeBSD 12.0-RELEASE amd64 with small patch (but the problem
with resume was same as with GENERIC kernel) so my battery can be
recognized:
https://bugs.freebsd.org/bugzilla/attachment.cgi?id=196523&action=diff

Unfortunately currently I don't have stock BIOS ACPI tables (then I
didn't know for acpica-tools package) but if needed I can flash stock
BIOS and dump ACPI tables.
Any ideas how to proceed with debugging?
