Known issues in Red Hat Enterprise Linux 6.4
System monitor displays incomplete processor information
Description The System Monitor does not display information for systems with processor cores greater than 20
(approximately).
Workaround For complete processor information in the /proc le system, run the following command:
Cat /proc/cpuinfo
This issue is also seen in Red Hat Enterprise Linux 6.3.
Cause lib gtop2, which is used by the System Monitor, has a limited buer size which results in incomplete processor
information being displayed.
Resolved issues in Red Hat Enterprise Linux 6.4
Power saving threads created by the acpi driver consumes
excess power
Description
The BIOS requests the acpi_pad driver for a specic number of processors to be moved into a High C state to
reduce power. The acpi pad driver creates a power saving thread on each processor to be idled.
Workaround Disable the acpi driver by appending acpi=o to the kernel boot command line of the /boot/grub/grub.conf le and
reboot the system.
This issue will be xed in a future release of Red Hat Enterprise Linux.
Cause The power saving thread loops very quickly consuming more power than it did before it was in an idle state.
Error message displayed on Dell EMC PowerEdge Servers with
AMD Opteron processors
Description
On installing and rebooting Red Hat Enterprise Linux 6.3 with AMD Opteron 43xx and 63xx processors, the dmesg
displays the following error message:
[Firmware Bug]: cpu 0, try to use APIC500 (LVT offset 0) for vector 0x10400,
but the register is already in use for vector 0xf9 on another cpu
[Firmware Bug]: cpu 0, IBS interrupt offset 0 not available
(MSRC001103A=0x0000000000000100)
Failed to setup IBS, -22
Workaround This issue is xed in Red Hat Enterprise Linux 6.4.
Cause The Local Vector Table (LVT) osets are not set up correctly. For Machine Check Exception (MCE) thresholds,
oset 0 is selected (indicated by banks 0-3) instead of 1 (bank 4). Instruction Based Sampling (IBS, IBSCTL
