I'm not sure what a "Linux v3.5" is - Montavista? There are patches
available from Motorola to the vanila kernel if you're interested in
using something newer than 2.6.15.

I'm using an MVME6100 with Linux 2.6.14 and experiencing what I think is
a cache coherency problem. An external PCIX master performs a DMA
transfer of a well known data pattern into SDRAM, but when the device
driver goes to look at the data it is mostly okay, but occasionally has
garbage.

Regarding the IVR patch: Have you seen this bug in practice, or just

There are several registers/etc that affect the caches on the Virtex4

Step 1 - Make sure your FPGA is configured to have caches in the memory
regions you're interested in caching. Your FPGA designer should have
done this in the EDK (check options in the MHS file).

I know this is probably a question for Freescale directly, but I thought
I would post here to see if anyone else has seen similar issues with the

I'm using a Freescale MPC85xx (8541) processor and seeing an extreme

Not so much a linux question, as a general MPC860 question, but maybe
someone out there can help.
