[openib-general] Error starting IB HCA while Linux Boot

[Adit Ranadive]

Hi,
I have a problem in getting the IB hardware during startup.
I am running a Red Hat Linux machine with Pentium D processors.
Here is the output of the dmesg command for the ib hardware:

ib_mthca: Mellanox InfiniBand HCA driver v0.06 (June 23, 2005)
ib_mthca: Initializing 0000:02:00.0
ib_mthca 0000:02:00.0: SYS_EN DDR error: syn=4, sock=0, sladdr=0, SPD
source=DIMM
ib_mthca 0000:02:00.0: SYS_EN returned status 0x07, aborting.
ib_mthca: probe of 0000:02:00.0 failed with error -22

Here is a detail of the IB hardware using the lspci command:
02:00.0 InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex
(Tavor compatibility mode) (rev a0)

Any idea why the IB hardware fails to start and is there a solution for this?

Thanks,
