Resolved issues in Red Hat Enterprise Linux 6.2
Errors found in command cat/proc/interrupts in Red Hat
Enterprise Linux 6
Description An error is displayed while running the command cat/proc/interrupts in Red Hat Enterprise Linux 6.
Cause The ERR interrupt occurs when the machine check code loads and initializes the thermal monitoring interrupt on
each core APIC. The BIOS generates a spurious interrupt on initialization.
biosdevname utility fails on NPAR capable network adapters
Description
The Red Hat Enterprise Linux 6.1 biosdevname utility incorrectly names the NIC partitions.
The biosdevname utility naming convention for NPAR capable network adapters is em <port number>_<NPAR
index>.
For example, the fourth NIC partition from the rst port of BCM 57712 dual port Network Daughter Card is em1_4.
The Red Hat Enterprise Linux 6.1 biosdevname utility incorrectly names the NIC partition as em5.
This will be xed in a future release of Red Hat Enterprise Linux.
Cause
The Red Hat Enterprise Linux 6.1 biosdevname utility incorrectly names the NIC partition because:
• The port number of the NIC partition does not match the actual number of physical ports present on the
system due to an issue in the NPAR partition naming logic in the biosdevname utility.
• The NPAR index is not suxed and there is an issue retrieving the NPAR index.
Known issues in Red Hat Enterprise Linux 6.1
Red Hat Enterprise Linux 6.1 displays a bluez network manager
error after installation
Description
After a clean install of Red Hat Enterprise Linux 6.1, the event log displays the following bluez error:
NetworkManager[9113]: <warn> bluez error getting default adapter: The name
org.bluez was not provided by any .service files
Workaround To prevent the message from reoccurring, run the following command: yum remove gnome-bluetooth
bluez.
NOTE: This issue is xed in Red Hat Enterprise Linux 6.4.
