I am currently working on getting OFED (an Infiniband stack) working on
an Extreme Engineering Xpdite4000
( http://xes-inc.com/Products/XPedite4000/XPedite4000.html ) with 2.6.11
(the vendor supplied kernel). 

The IB code calls dma_alloc_consistant 1024 times which then calls
vm_region_alloc. On the 501st iteration vm_region_alloc fails because
addr is greater than end (nospc). 

With that known, I am curious as to what would cause that type failure
and what potential fixes there are for it.

Thanks,
Owen
