Not so sure a backtrace will help much here as SIGIO is an external async
event.. but maybe.
SIGIO generally indicates there is a filedesriptor opened (or fcntl:ed)
with the O_ASYNC flag and that I/O is now possible on that filedescriptor.
Another possibility is that you are holding a file lease (fcntl
F_SETLEASE).
Or that an external process sent you a SIGIO.
Maybe more, but these are the cases I know of.
