Subject: An error about block I/O subsystem

I have implented an I/O scheduler in Linux 2.6.But when I use fio to
test it,the kernel message often print some words,like this
"deadline_rb: forced dispatching is broken (nr_sorted=1),please report
this"

I have no idea about it,maybe my scheduler has some problems.But I
want to know why!
Thank you!
