Seems most of the file-io processes are hung trying to open a file: [root@...011-12060006 lanforge]# cat /proc/10612/stack [<ffffffff8115fadb>] do_last+0x1db/0xa4e [<ffffffff8116090b>] path_openat+0xcb/0x363 [<ffffffff81160ca8>] do_filp_open+0x38/0x84 [<ffffffff81153bfc>] do_sys_open+0x6d/0xff [<ffffffff81153cbb>] sys_open+0x1c/0x1e [<ffffffff8154f629>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff I'm going back to 3.7.3 and will try to learn some more about what it's doing there.
