I've been using the ql2400_fw.bin from the qlogic ftp after putting it in /lib/firmware for a week or two now with the following dual 4GB FC HBA: 0001:06:03.0 Fibre Channel: QLogic Corp. ISP2422-based 4Gb Fibre Channel to PCI-X HBA (rev 02) 0001:06:03.1 Fibre Channel: QLogic Corp. ISP2422-based 4Gb Fibre Channel to PCI-X HBA (rev 02) It works fine on ppc64.
thanks. added ~ppc64 to latest version.
