https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D245654 --- Comment #10 from Vladimir Kondratyev <wulf@freebsd.org> --- (In reply to xspbe3ho3p5uac from comment #9) There are only 6 /dev/iic* rather than 7. One device is still not configure= d. It looks like your ACPI BIOS has so called I2C OpRegion handler. I ported support for it from DragonFlyBSD recently but it is disabled by default as = non tested. It is used by ACPI BIOS to communicate with peripheral devices e.g. battery charge controllers over I2C bus. It can be enabled with placing following l= ine to /boot/loader.conf: hw.iicbus.enable_acpi_space_handler=3D1 You should reboot after that. I do not know how to test it though. Maybe verbose boot will reveal some debugging messages. --=20 You are receiving this mail because: You are the assignee for the bug.=
