https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238037 --- Comment #12 from Austin Shafer <ashafer@badland.io> --- Created attachment 205573 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D205573&action= =3Dedit ig4 suspend with devidle set [needs testing] Thanks for the input. Placing the device in the idle state before suspending sounds like a good idea. The PCH datasheet does have a note saying this sho= uld be done before any resets so I think you are right. Maybe I missed something trivial while reading the datasheets, but why in `ig4iic_attach` is this on= ly done for skylake and not also done for haswell? I went ahead and added this to a new patch, it would be amazing if someone could try it out and let me know if it makes any difference. Thanks! --=20 You are receiving this mail because: You are the assignee for the bug.=
