pci_enable_msi() will checking your device whether it supports MSI.
Can you provide the detailed lspci information ? eg. lspci -vvvxxx ?

How to check for proper MSI support?
...ns 1, suggesting
that it supports MSI. However, this "00:0e.0 PCI bridge: PLX
Technology, Inc. PEX8112 x1 Lane PCI Express-to-PCI Bridge (rev aa)"
is a component of the addin card. Wouldn't the lack of support for MSI
by the chipset "00:00.0 Host bridge: Intel Corporation 430FX - 82437FX
TSC [Triton I] (rev 01)" preclude the use of MSI with buses attached
via a bridge?
Thanks,

...= pci_enable_msi(device->pdev) == 0;
Does it need to do more checking than that before trying to enable MSI
on the device? Could it be that the linux pci subsystem is missing on
inheriting MSI capabilities somewhere?
Thanks,

We have no ways to check host bridge whether support MSI routing to CPU, BIOS
is responsible for setting and config this in their private registers located in IOH.
This is transparent to OS I think....
