information will be displayed in dmesg:
ERST: Error Record Serialization Table (ERST)
support is disabled.
15776200 Hardware error messages and false mcelog errors appear in dmesg on two-processor and four-
processor server configurations running SLES 11 SP2.
Issue:
The following error message might appear when running SLES 11 SP2 on a two-processor or four-
processor system:
MCE Error, Status code: d00001000009008f
Affected Operating System:
■ SUSE Linux Enterprise Server (SLES) 11 SP2
Workaround:
If the error messages are not persistent, and there is no obvious performance degradation, you
can safely ignore them. If the error messages are persistent, identify and replace the marginal
components.
15780082
Value of the crash kernel option for RHEL 5.8 and Oracle Linux 5.8 needs to be increased to a
minimum of 128M@32M.
Issue:
When using the Oracle Unbreakable Enterprise Kernel for Linux, a higher memory
setting is required for the crash kernel option in the
/etc/grub.conf
file. Booting with
crashkernel1=128M@16M
results in the following error:
crashkernel reservation failed -
memory is in use.
Affected Operating Systems:
■ Oracle Linux 5.8
■ Red Hat Enterprise Linux (RHEL) 5.8
Workaround:
The minimum value for the crash kernel option is 128M@32M. Based on the system configuration,
an even higher value might be required. If
kdump
service loading fails, increase the second value
(32M). If the system hangs or crashes during dumping the core, increase the first value (128M).
15759139 Quad Gigabit Ethernet UTP PCIe and Dual Gigabit Ethernet PCIe option cards do not work
on SLES 10 SP4 XEN.
Issue:
On SLES 10 SP4 XEN, the Quad Gigabit Ethernet UTP PCIe (X4446A-Z) and the Dual Gigabit
Ethernet PCIe (X7281A) do not work normally because of a XEN kernel issue.
