Comment 8 Richard A Lary 2009-10-02 11:36:51 EDT

On PowerPC platforms an additional step is required to realize the full effect of this qlge driver fix. The qla2xxx driver must be configured to use MSI-X interrupts instead of default INTA interrupts.  

Configure the qla2xxx driver to load with ql2xenablemsix=1 by adding an options line for qla2xxx to /etc/modprobe.conf or appending this option to an already existing options qa2xxx line. 

options qla2xxx ql2xenablemsix=1

After making this change to /etc/modprobe.conf a new initrd must be built as qla2xxx driver loads at boot.

See Red Hat documentation for how to build new initrd.
