mpc8248 SEC -- interrupt handler "is" invoked

[Vikas Aggarwal]

Tried it as u said . No luck :(
But something more i noted now in CPSR(channel pointer status
register=0x2040)  that before ISR invoked it has 0x0:0x7.

After ISR invoked it has 0x7:0x2007 .  The 7 in low bits means
channel_error and 2 is at "reserved" bits as per documentation, don't know
what that means.

I also tried kmalloc with GFP_DMA, for the memory where i create the
Descriptor.
Please keep giving ideas for debugging this as this is what driving me
right now.
regards
