events through gnome-bluetooth module.
Error message on starting IPMI drivers while installing OMSA
Description On starting the IPMI service on PowerEdge R620, T620, M620, R720, and R720xd systems, the system log
displays the message: Could not enable interrupts, failed set, using polled mode.
Workaround This is working as designed. This is addressed in a later version of the iDRAC rmware.
Cause Although the message indicates that the operating system is in polling mode, the Linux driver continues to work in
the interrupt mode.
Assigning iSCSI LUN target to Intel 10G network controller
stops the operating system from booting
Description When attempting to install the operating system on iSCSI Logical Unit Numbers (LUN) with the Intel 10G network
controller (Intel card X520 and Intel Ethernet X520-DA2 Server Adapter), the system stops responding at the boot
screen (after POST).
Workaround Disable the local storage controller from the BIOS menu, and then proceed with the iSCSI based installation.
Cause This error occurs because the BIOS 0xE820 code does not return the rst 0xe820 entry to match int 12 interface
and hence does not comply with ACPI specication.
Systems with Intel multiport i350 rNDC and PCI add-in
adapters report incorrect or duplicate Mac address
Description
Native igb driver reports incorrect MAC ids for interfaces of multiport i350 rNDC and PCI add-in adapters. This
results in interface congurations les ifcfg-ethN having incorrect HWADDR elds.
This issue is addressed in the latest version of the Dell EMC igb driver. Use the latest driver disk from
www.dell.com/support during installation, to address this issue. This ensures that interface congurations les will
have correct MAC ids.
Workaround
During Installation, load the Dell EMC DKMS drivers on to a USB drive in the form of a driver disk. The Anaconda
installer uses these drivers and updates the original drivers.
To install the drivers:
• During installation: Load the Dell EMC DKMS drivers on to a USB drive in the form of a driver disk. The
Anaconda installer uses these drivers and updates the original drivers.
• During upgrade: Network conguration les are created using the original drivers during installation. Due to this,
the conguration les retain the faulty MAC address. Delete all the conguration les present in the scripts
directory /etc/syscong/network-scripts/ifcfg-*, and restart the server.
