As a workaround, the v0.8.0 FPGA image for the x115 seems to work okay: https://www.nuand.com/fpga_images/

My current theory is that the SPI controller/arbiter are in the wrong clock domain, resulting in unexpected (and incorrectly-defined) clock domain crossings. Some builds will be fine, others will fail.
