Please try this, which will poke that same system
call in a different way:

  rm -f foo foolink
  touch foo
  ln -s foo foolink
  lsextattr -h user foolink
  lsextattr -h user foo
  setextattr user test test foo
  lsextattr -h user foolink
  lsextattr -h user foo
  setextattr user test test foolink
  lsextattr -h user foolink

I'm especially curious about the processor and
filesystem you're using when you see these problems.

Cheers,

Tim
