Thanks kumar,
I've got the patch out which fixes the issues. 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".
Thanks in Advance.
