New Kernel: 2.6.18-338.19.1.el5.lve0.8.36

New kernel 2.6.18-338.19.1.el5.lve0.8.36 is available now. The kernel brings changes from upstream kernel (OpenVZ 028stab092.2), as well as improves load averages reporting. The kernel has following bug fixes and enhancements:
  • Rebase on 238.19.1 rhel5.6 update (security and bug fixes RHSA-2011:0927-1 )
  • DRBD is compiled in xen x86_64 kernels
  • OpenVZ kernel related bugfixes (more)
  • Improved load averages
In previous kernel versions, load averages wouldn't include processes in D state (uninterruptible state). Those are the processes that are waiting on IO. This kernel fixes the issue. You can switch back to old behavior by running:

sysctl -w kernel.full_loadavg=0


or adding it to /etc/sysctl.conf  and run sysctl -p


To install new kernel:
Code
# yum install kernel-2.6.18-338.19.1.el5.lve0.8.36


If you have PAE, xen or Enterprise kernel -- use corresponding prefix, like: kernel-PAE, kernel-xen, kernel-ent instead of kernel
