However I couldn't spot anything further regarding 'battery|BAT0', and you did catch the start of initialisation. I'm out of my depth, but you might also try layer 'ACPI_EC' with high verbosity? You shoudn't need to reboot to try things now that ACPI_DEBUG is enabled in your kernel; you can adjust them on the fly. From section 11.16.6 on the acpi-debug page: "If the information you want is triggered by a specific event (say, a suspend and then resume), you can leave out changes to loader.conf and instead use sysctl to specify the layer and level after booting and preparing your system for the specific event. The sysctls are named the same as the tunables in loader.conf." So you could avoid all the boot messages, if they're not helpful, and log events like switching from AC to battery and vice versa, which might trigger interrogating the battery (via the EC, probably), by adjusting those sysctls, just for an example: root# sysctl debug.acpi.layer="ACPI_EC ACPI_BATTERY ACPI_AC_ADAPTER" root# sysctl debug.acpi.level="ACPI_LV_VERBOSITY3" But I'm just stabbing in the dark, really .. good luck. cheers, Ian > 2014-07-15 20:22 GMT+02:00 Ian Smith <smithi@nimnet.asn.au>: > > > On Tue, 15 Jul 2014 19:49:46 +0200, Daniele Mazzotti wrote: > > > > > I made a few step ahead (at least on my side) and tried to follow the > > > recommendation from the handbook ( > > > http://www.pl.freebsd.org/doc/handbook/acpi-debug.html). > > > > > > I was able to turn on the verbose boot and here you can find the output: > > > http://pastebin.com/kkDAZEVb.
