RHBA-2012:1093 - Bug Fix Advisory
Synopsis
kernel bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated kernel packages that fix one bug are now available for Red Hat
Enterprise Linux 5.3 Long Life.
Description
Problem Description:
The kernel packages contain the Linux kernel, the core of any Linux operating
system.
This update fixes the following bugs:
- An insufficiently designed calculation in the CPU accelerator in the previous
kernel caused an arithmetic overflow in the sched_clock() function when system
uptime exceeded 208.5 days. This overflow led to a kernel panic on the systems
using the Time Stamp Counter (TSC) or Virtual Machine Interface (VMI) clock
source. This update corrects the described calculation so that this arithmetic
overflow and kernel panic can no longer occur under these circumstances.
(BZ#835447, BZ#825979)
All users are advised to upgrade to these updated packages, which fix these
bugs.
