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.
