As I wrote in the initial bug report, the problem has been introduced _after_ kernel 3.10, facd23664f1d63c33fbc6da52261c8548ed3fbd4 is _not_ part of kernel 3.10.x Therefore the CC to stable@vger.kernel.org for v3.10 in b9a1dfd3ba3ae00b0c1d1a396ed43fac85a32990 is wrong. cu, Knut > Regards, > > Hans > > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
