The activity just prior to the sync is not significant: the previous
filesystem calls are just writing back to the buffer cache, and all of
those changes don't hit disk until the sync().
Could you find the "wchan" of the stalled process and look it up in
System.map? The wchan is displayed in "ps -l" output, and will be
looked up automatically if the appropriate System.map is in /boot
(either as /boot/System.map-2.?.??? (fill in the blanks) or
/boot/System.map).
