[openib-general] Trouble with 2.6.20 and QLE7140/ipath driver

[Roland Fehrenbacher]

Hi,

trying to load the ib_ipath module with a 2.6.20-rc4 kernel, I obtain:

---------------------------------------------------------------------------

---------------------------------------------------------------------------

and the link of the QLE7140 remains down. I looked at the Pathscale
patches for kernel 2.6.16, but it seems these fixes are already
integrated into 2.6.20.

lspci shows that the PCIe slot supports MSI:

Any idea how I can get the card to work? Using 2.6.18.3 with
ipath_core/ib_ipath the card works ok (apart from a bug I hit with
Lustre, but that's another issue). 2.6.19.x has the same problems as 2.6.20.

The hardware is a ASUS Dual Opteron board (Nvidia chipset nForce4 2200
Professional) with 280 CPUs.

Thanks,
