https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D245654 --- Comment #8 from Vladimir Kondratyev <wulf@freebsd.org> --- (In reply to xspbe3ho3p5uac from comment #7) > this machine doesn't actually seem to have any devices attached on the I2= C bus. This machine have at least 3 I2C devices defined in DSDT table. You can find them with searching of "devinfo -rv" output for 'handle=3D\_SB_.I2C' string= . I doubt that they can be used for something good, but it would be nice to rea= d at least 1 byte from any of them. BayTrail is known for sharing I2C lines with power management unit so I would like to know if I2C works at all without dedicated support for this unit. Could you post output of "sudo acpidump -dt" command here too. It looks like one of I2C devices were not recognized properly by ACPI subsystem. --=20 You are receiving this mail because: You are the assignee for the bug.=
