Details

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.

This update fixes the following bugs:

* 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#951720)

* 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#975524)

* 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. (BZ#991363)

Users of irqbalance are advised to upgrade to these updated packages, which fix
these bugs.
