Yes Adrian, it should be 2.15 instead. My mistake.

Hopefully this patch should solve steve's issue too.

Reattaching the patch with corrected changelog.

Thanks

o i386 kernel reboots instantly if compiled with binutils older than
2.15.

o Older binutils required explicit flags to mark a section allocatable
and executable(AX). Newer binutils automatically mark a section AX if
the name starts with .text.

o While defining a new section using assembler "section" directive,
explicitly mention section flags.
