The reason this happens is simple. In vfp_get_double(), we have: 1: fmrrd r0, r1, d\dr 1: mrrc p11, 3, r0, r1, c\dr @ fmrrd r0, r1, d\dr but in vfp_put_double(), we have: 1: fmdrr d\dr, r0, r1 1: mcrr p11, 3, r1, r2, c\dr @ fmdrr r1, r2, d\dr Note the different registers. Change "r1, r2" to "r0, r1" and it should work. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
