[ofa-general] Loading of ib_mthca fails

[Xavier Andrade]

Hi,

I have the following problem with an Infiniband adapter, when I tried to 
load the kernel module ib_mthca I get the following error:

ib_mthca: Mellanox InfiniBand HCA driver v0.08 (February 14, 2006)
ib_mthca: Initializing 0000:04:00.0
ACPI: PCI Interrupt 0000:04:00.0[A] -> GSI 17 (level, low) -> IRQ 17
PCI: Setting latency timer of device 0000:04:00.0 to 64
ib_mthca 0000:04:00.0: MAP_FA returned status 0xff, aborting.
ib_mthca 0000:04:00.0: Failed to start FW, aborting.
ACPI: PCI interrupt for device 0000:04:00.0 disabled
ib_mthca: probe of 0000:04:00.0 failed with error -22

Kernel (and ib driver) is stock 2.6.24.2 x86_64 and distribution Debian 
4.0.

The card is an Intel Inifiniband I/O Expansion module (AXXIBIOMOD) 
installed in a Intel S5000PAL motherboard. This the pci info of the 
adapter:

04:00.0 InfiniBand [0c06]: Mellanox Technologies MT25204 [InfiniHost III Lx HCA] [15b3:6274] (rev a0)

Does someone know where the problem can be?

Thanks,

Xavier
