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.

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.

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

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 third-
party 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.
