            Bug ID: 22985
           Summary: ld: linux kernels built with 2.31 do not boot
           Product: binutils
           Version: 2.31 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org

  Target Milestone: ---

Hello,

Linux kernels built with binutils HEAD, starting some time after 27.02.2018, no
longer boot, but immediately cause a reboot.

The final vmlinux binary is ~5MB smaller (out of ~600MB), and the .text section
starts at 0x1000, instead of the usual 0x20000:

I'll try to find the culprit via bisection, last working version I have is HEAD
as of 27.02.2018.

Thanks!
