When you do test mainline and bisect, could you also test this attached pat= ch? I suppose when UCSI_GET_PDOS fails we could reset PPM and retry the read o= nce. Also, did you perform a firmware or bios update around same time? --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
