8.76. irqbalance

Updated irqbalance packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The irqbalance packages provide a daemon that evenly distributes interrupt request (IRQ) load across multiple CPUs for enhanced performance.

Bug Fixes

Previously, irqbalance warned about MSI interrupts, and that IRQs would not be properly classified due to the use of a kernel version older than kernel-2.6.32-279. This update blocks users from using irqbalance with an older version of the kernel, without features required for processing MSI interrupts, and warning messages are no longer received.
Due to recent changes in the irqbalance packages, the /var/run/ file was not created upon start of the irqbalance service, causing irqbalance to become non-compliant with the Linux Standard Base (LSB) specification. This update provides a patch fixing this problem so the irqbalance packages are LSB compliant again.
A bug in the irqbalance code caused the irqbalance daemon to terminate with a segmentation fault when a CPU was hot plugged or hot unplugged. This update fixes a corrupted IRQ rebalance list and the irqbalance daemon no longer crashes in this scenario.
Users of irqbalance are advised to upgrade to these updated packages, which fix these bugs.
