Monthly Specification Update Enterprise Platforms and Services Marketing Workaround If a specific hardware configuration experiences this issue, remove the add-in PCI and PCI Express* cards to reduce the amount of add-in card resource space used. Perform the system update (BIOS, FRUSDR) and replace the add-in cards when updates are completed. 29. Intel® Embedded Server RAID Technology II and I/O module IRQ routing conflict Problem If the Intel® Embedded Server RAID Technology II is enabled in the BIOS while an I/O module is installed, the system hangs at the RAID Option ROM on the next reboot due to the RAID device's IRQ not being serviced properly. Implication The Intel® Embedded Server RAID Technology II option in BIOS cannot be used while an I/O module is installed in the system. Status This erratum is fixed since BIOS release R0061 and later releases. Workaround None. 30. SuSE* Linux Enterprise Server may not install successfully with Intel® Embedded Server RAID Technology II enabled Problem If SuSE* Linux Enterprise Server is being installed with Intel® Embedded Server RAID Technology II enabled, the RAID array may not be detected after the driver is loaded, which results in an installation failure. Implication The AHCI.o module inside the operating system is loaded prior to the thirdparty driver and, therefore, may take control of the RAID controller. This results in an installation failure. Status Users cannot load a third-party RAID driver and the AHCI driver simultaneously in SuSE* Linux Enterprise Server. Doing so may cause installation failures. Workaround The "brokenmodule-ahci" command can prevent AHCI from loading during installation. At the very first install screen, press F6 to load a driver. In the text tab, type brokenmodules=ahci This allows the installation to complete successfully. 15
