[openib-general] hotplug and mthca

    Hal> Hi, When I start mthca, I get the following:

    Hal> /sbin/hotplug: no runnable /etc/hotplug/infiniband.agent is
    Hal> installed

That's benign -- hotplug gets an event when
/sys/class/infiniband/mthca0 is created but it doesn't have a script
for handling the infiniband class.

    Hal> How does one get mthca to load automatically ?

If ib_mthca.ko is in /lib/modules/xxx for your boot kernel, hotplug
should load it automatically on boot; it matches the HCA PCI device
with the signature in ib_mthca.ko (the

alias:          pci:v000015B3d00005A44sv*sd*bc*sc*i*
alias:          pci:v00001867d00005A44sv*sd*bc*sc*i*

part of modinfo output).
