Re: Cannot create Segment or Container or Region at arm platform

Hi Michael,

   Yes. I have tried on ARM before. There is an issue here around the
O_DIRECT calls and how it is being implemented in the kernel.

Please trace this ' Strange EVMS/MD behavior on Intel XScale
processor<http://marc.info/?t=115945557900003&r=1&w=2>
'

*on this list and the replies on it. It might be useful.

*


Thanks
