Bisection has been finished (I'm usually away from the problematic computers in summer), result is strange and seems unrelated: 0bc5fe857274133ca028ebb15ff2e8549a369916 is the first bad commit commit 0bc5fe857274133ca028ebb15ff2e8549a369916 Author: Sudarsana Reddy Kalluru Date: Sat May 5 18:42:59 2018 -0700 qed*: Refactor mf_mode to consist of bits. `mf_mode' field indicates the multi-partitioning mode the device is configured to. This method doesn't scale very well, adding a new MF mode requires going over all the existing conditions, and deciding whether those are needed for the new mode or not. The patch defines a set of bit-fields for modes which are derived according to the mode info shared by the MFW and all the configuration would be made according to those. To add a new mode, there would be a single place where we'll need to go and choose which bits apply and which don't.
