5 update 7 errata kernel, a symbolic link is created from the weak-updates of the errata kernel
to the extra directory of Red Hat Enterprise Linux 5 update 7 kernel.
The weak-updates modules have lower preference than the built-in modules for the errata
kernel as defined in the file /etc/depmod.d/depmod.conf.dist. As a result, when the system
boots into the errata kernel, the built-in module is loaded instead of the Dell dkms module,
causing the issue to re-appear, if the built-in module of the errata kernel has the issue. This
can be prevented by overriding the default module load search preference for the igb module,
before booting into the errata kernel.
This issue is fixed in Red Hat Enterprise Linux 5 update 8.
System Hangs Intermittently While Booting
Description Certain systems with 4x 10-core processors (80 logical CPUs with hyperthreading enabled)
hang intermittently while booting. On a typical system this problem is seen in less than an hour.
Workaround This issue is fixed in Red Hat Enterprise Linux 5 update 8.
Red Hat Enterprise Linux 5 Update 7 Not Available In SBUU And USC Installation Methods
Description When attempting to install the operating system through SBUU and USC installation methods,
the Red Hat Enterprise Linux 5 update 7 option is not available.
The affected operating system is Red Hat Enterprise Linux 5 update 7 (32- and 64- bit).
Workaround Install Red Hat Enterprise Linux 5 update 7 using manual methods, and download the relevant
drivers from dell.com/support.
A fix for this will be available in a future update to Red Hat Enterprise Linux 5.
Cause The Red Hat Enterprise Linux 5 update 7 option has been removed from SBUU and USC
installation methods due a bug identified in the operating system that causes dkms driver
modules to corrupt the driver database. This results in kernel panic and boot-loader problems.
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 first 0xe820 entry to
match int 12 interface and hence does not comply with ACPI specification.
Error Message On Starting IPMI Drivers While Installing OMSA
Description On starting the IPMI service on Dell PowerEdge R620, T620, M620, R720, and R720xd systems,
the system log displays the message: Could not enable interrupts, failed
set, using polled mode.
