thanks to all
We are using the AMD-8131 and that explains it.

Hello Ron,

Looks to me like MSI is enabled in recent stock FC2 and FC3 2.6.9+
X86_64 kernel builds, so a driver that cannot be told not to use MSI if
it is available (as I believe is the case with the current Mellanox
vapi-4.0.1 release) would not seem to have a good chance of working on a
stock FC2 or FC3 kernel when a AMD-8131 chipset is involved.
