Hi list and Michael - I received a T470s at work and decided to jump into the CURRENT end of the FreeBSD pool. I have a weird acpi_ibm issue and I'm not sure where to start trying to diagnose the issue. # uname -a FreeBSD spanner 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r328126: Thu Jan 18 15:25:44 UTC 2018 root@releng3.nyi.freebsd.org:/ usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 I've loaded acpi_ibm via /boot/loader.conf: acpi_ibm_load="YES" and the module shows as being loaded: # kldstat | grep acpi_ibm 8 1 0xffffffff8278e000 7570 acpi_ibm.ko However, I don't have any of the sysctl knobs available; e.g. # sysctl -a | grep acpi_ibm # or # sysctl dev.acpi_ibm.0.fan_speed sysctl: unknown oid 'dev.acpi_ibm.0.fan_speed' I've (tried) to look through the commit messages on svn-src-head, but I'm not seeing anything specifically related to acpi work, or I just don't know what I'm looking at (a definite possibility). Would someone be able to provide a bit of debugging direction here? Reviewing `dmesg -a` doesn't tell me anything specific about acpi_ibm. Thanks in advance for your time and trouble. Bridger
