Could you point me > out which commit it is? Thanks No. I mean that suspend generally works in 4.14 and is currently broken in 4.15-rc which requires a fix to be applied. The fix in question is at: https://lkml.org/lkml/2017/11/30/546 This is needed due to some changes made in 4.15-rc (with respect to 4.14) that broke resume from suspend to RAM. Thanks, Rafael
