Installation guide

the following:
EDAC MC: Ver: 2.0.1 Oct 4 2008
EDAC MC0: Giving out device to cell_edac MIC: DEV cbe-mic
EDAC MC1: Giving out device to cell_edac MIC: DEV cbe-mic
If correctable memory errors are encountered, the following message will be returned to the console:
EDAC MC0: CE page 0xeff, offset 0x5700, grain 0, syndrome 0x51, row 0, channel
0, label "":
Debugging with hardware watchpoints using a variable that is shared between multiple threads was
causing the GNU Debugger (GDB) to erratically miss trigger events. T he kernel has been updated to
allow GDB to consistently receive the watchpoint triggers, improving the reliability of the debugging
session.
5.4. x86_64 Architectures
kprobe-booster is now supported on the ia64 and x86_64 architectures, allowing users to probe
kernel events much faster. This feature will also decrease the overhead caused by probing tools
(e.g. SystemTap and Kprobes) on servers running on 64-bit architecture.
Support has been added to the kernel for the _PT C (Processor Throttling Control), _TSS (Throttling
Supported States) and _TPC (Throttling Present Capabilities) objects. This support, which is part of
the Advance Configuration and Power Interface specification (ACPI) provides improved management
of processor throttling.
5.5. s390x Architectures
In zipl.conf, parameters enclosed with double quotes inside of single quotes (ie
param eters='vm halt="LOGOFF"') were being parsed incorrectly. Consequently, installing the
kernel-kdump package may have failed, resulting in the error:
grubby fatal error: unable to find a suitable template
To resolve this issue, parameters should be enclosed with single quotes inside of double quotes (ie
param eters="vmhalt='LOGOFF'")
Note
The syntax structure of single quotes inside of double quotes is the default in Red hat
Enterprise Linux 5.
5.6. ia64 Architecture
The Dual-Core Intel Itanium 2 processor filled out machine check architecture (MCA) records
differently to previous Intel Itanium processors. T he cache check and bus check target identifiers can
now be different in some circumstances. The kernel has been updated to find the correct target
identifier.
kprobe-booster is now supported on the ia64 and x86_64 architectures, allowing users to probe
kernel events much faster. This feature will also decrease the overhead caused by probing tools
(e.g. SystemTap and Kprobes) on servers running on 64-bit architecture.
