Timer Driver

Hi all,

I am trying to port RTEMS to an Avnet MCF5282 eval board and I am having trouble 
running some of the timing test suite programs. I have been modifying the code from 
the uC5282 BSP package on the cvs. I have the board booting from flash and it runs 
the hello world and ticker sample programs just fine. The first two timing test suite 
programs run fine, but the third test errors while printing out the first statement:

*** TIME TEST 3 ***
rtems_semaphore_release: tas

I have the clock driver running from a programmable interrupt timer(PIT3) and is set 
to about 1 microsecond. The system clock of 58.976MHz is being prescaled by 64. 
For the timer driver I am using a DMA timer that also prescales the system clock by 
64. Does anyone know why this would crash some of the timing test suite programs? 
I'd appreciate any and all help. Thanks for your time.
