Unfortunately, I'm still seeing hangs in generic/299 with the latest version of fio: fio fio-2.14-10-g0a301e9 (Fri, 23 Sep 2016 11:57:00 -0600) If I use an older fio, it reliably does not hang. What can I do to help debug this? As I said, I can attach to the hanging fio using a gdb and give you stackdumps for all of the threads if that would be helpful. - Ted -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
