msdos_format - deadlock

[Federico Garcia Cruz]

I'm using rtems version 4.10.99.0 (trunk 2014-07-04). We have developed a
bsp for lpc1768 and it's already uploaded to rtems trunk.
I've done some debugging and the program get stuck waiting for a bdbuf to
be free. Function rtems_bdbuf_get never gets a free buffer and then it
calls to rtems_bdbuf_wait_for_buffer and it never returns.
How can I test plain block read/write transfers?
