[ewg] OFED 1.2.5 issue with MSI ??

[Arlin Davis]

I just noticed when setting up MSI support that ib_mthca fails with the following:

This is on 2 different Intel platforms that worked with OFED 1.2:

ib_mthca: Mellanox InfiniBand HCA driver v0.08 (February 14, 2006)
ib_mthca: Initializing 0000:0a:00.0
ACPI: PCI interrupt 0000:0a:00.0[A] -> GSI 16 (level, low) -> IRQ 169
PCI: Setting latency timer of device 0000:0a:00.0 to 64
ib_mthca 0000:0a:00.0: NOP command failed to generate interrupt (IRQ 233), aborting.
ib_mthca 0000:0a:00.0: Try again with MSI/MSI-X disabled.
ib_mthca: probe of 0000:0a:00.0 failed with error -16

Anyone else see this issue?
