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

BZ#951720: 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.
BZ#975524: Due to recent changes in the irqbalance packages, the /var/run/irqbalance.pid 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.
BZ#991363: 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.
