Re: kernel 2.6.15: cpm_uart driver broken?

Hi,

I've found this thread, but I haven't seen the end of the discussion. I=
 am
using this kernel version, and I am also having problems with the cpm_u=
art.
Only the console (SMC1) is working, the other devices working as uart f=
ail.
I've realised that the problem is in the DMA. The system crash when the=
 Rx
and Tx buffers are allocated in external memory (in case of allocating =
in
the DPRAM of my mpc866, it works properly) and I don't know why. It is
supposed other devices (as fec) use the same functions
("dma_alloc_coherent") and they work.

Moreover I don't find any documentation about the parameters
"CONFIG_CONSISTENT_START" and "CONFIG_CONSISTENT_SIZE". Does these
parameters affect to the driver behaviour?

Could anyone help me?

Kind regards,

Ra=FAl Moreno
