But now.. seems there is some generic issue in PPC440 targets, I am observing that *remap_file_pages01* and *remap_file_pages02 *test cases from LTP are failing since *Linux-2.6.24* kernel to *Linux-2.6.30*. If you can give some pointers that would be greatly appreciated ! Or if you have results for this on any PPC44x would be helpful. Arch : PowerPC Target : Xilinx PowerPC440 virtex5 I've tried to test the cause for this but found that kernel throws error message of "segmentation fault".
