       This is rank.  0x2000 was used to detect the trailing edge of ring.
       The leading edge is detedted by EV_RING.

       The trailing edge is reliable.  The leading edge is not.
       Softie no longer allows the trailing edge to be detected in NTsp2
       and beyond.

       So... Try the reliable option above and if it fails, use the less
       reliable means.

       The screams for a giveio solution that bypasses the kernel.
