Seems most of the file-io processes are hung trying to open a file: [root@lf1011-12060006 lanforge]# cat /proc/10612/stack [] do_last+0x1db/0xa4e [] path_openat+0xcb/0x363 [] do_filp_open+0x38/0x84 [] do_sys_open+0x6d/0xff [] sys_open+0x1c/0x1e [] system_call_fastpath+0x16/0x1b [] 0xffffffffffffffff I'm going back to 3.7.3 and will try to learn some more about what it's doing there.
