PCI: Unable to reserve mem region

[Shirley Ma]

When I loaded Mellanox device driver on P615, I hit below problem:

Mar  2 14:31:39 elm3b5 kernel: ib_mthca: Initializing  (0000:62:00.0)
Mar  2 14:31:39 elm3b5 kernel: PCI: Enabling device: (0000:62:00.0), cmd 
142
Mar  2 14:31:39 elm3b5 kernel: PCI: Unable to reserve mem region 
#5:8000000 at 3fcc
0000000 for device 0000:62:00.0
Mar  2 14:31:39 elm3b5 kernel: ib_mthca 0000:62:00.0: Cannot obtain PCI 
resource
s, aborting.
Mar  2 14:31:39 elm3b5 kernel: ib_mchca: probe of 0000:62:00.0 failed with 
error
 -16

Anybody has any idea to fix this problem?

Thanks
