Ah, mlx4_core was already loaded. After unloading it and loading mlx4_ib
again I also get kernel messages.

[10010.988484] mlx4_core: Mellanox ConnectX core driver v0.01 (May 1, 2007)
[10010.988490] mlx4_core: Initializing 0000:09:00.0
[10010.988532] ACPI: PCI Interrupt 0000:09:00.0[A] -> GSI 18 (level, low) -> IRQ 18
[10010.988555] PCI: Setting latency timer of device 0000:09:00.0 to 64

At least defining the ib0 interface works now, too. Presently can't further
test it now, since its connected to a flaky mts2400 switch, which needs a 
reset.

Hmm, I already grepped there. Will look tomorrow again.

Btw, does the mlx4 driver in 2.6.22 work reliable or have 
their been major issues fixed in 2.6.23?


Thanks a lot for your help,
