Hi,

Wrt. the build environment, the built kernel/modules can work fine just after
switching gcc from gcc-5 to gcc-4.9 and keep other things not changed
in Xenial.

So I am sure the issue is in Xenial gcc-5, and the bug should be introduced
after 5.2.1-22ubuntu2 because Wily gcc-5 hasn't this problem.

thanks,

Title:
  arm64: "unsupported RELA relocation"

Status in gcc-5 package in Ubuntu:
  New
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  linux-image-4.3.0-5-generic 4.3.0-5.16 arm64 fails to load modules
  (and therefore boot). It emits messages like the following for each
  attempted module load:

  [    2.156817] module libahci: unsupported RELA relocation: 275

  This is reminiscent of LP: #1502946 - except that fix appears to still
  be in-tact. What has changed, however, is the build environment. If I
  rebuild the same kernel source in a wily chroot, it boots fine.

  Marking "Confirmed" because Paulo Pisatti reported this to me, and I
  reproduced.
