HI,

HP DL365 Server
OS: RedHat Enterprise 5
Kernel: 2.6.18-8

getting the following error messages in the /var/adm/messages log.

kernel: powernow-k8: error - out of sync , fix 0x2 0x2, vid 0x12 0xc

What could be the issue. Please suggest.

You seem to be running a RHEL 5.0 kernel, with no patches installed.

RedHat Bugzilla lists plenty of severe powernow-k8 bugs as fixed in 5.2 or 5.3:

https://bugzilla.redhat.com/buglist.cgi?query_format=specific&order=relevance+desc&bug_status=__all__&product=Red+Hat+Enterprise+Linux+5&content=powernow-k8

What's the generation number of your server? If it's G5, you need at least the RHEL 5.1 update level; some particular processor models require 5.2. See this RedHat Knowledge Base document:

http://kbase.redhat.com/faq/docs/DOC-16313

HP also confirms that RHEL 5.1 is minimum required on DL365 G5:

If your system is registered to RedHat Network and your subscription status is OK, just run "yum update" to upgrade your system to RHEL 5.4 automatically. You will need to reboot to activate the updated kernel, but the update mechanism does not require you to reboot immediately: you can e.g. install the updates now and schedule the reboot to next night/weekend/other scheduled maintenance time.

Thanks for help.
But our server can't direct connect to internet. Can I just update kernel build to fix the issue? (kernel-2.6.18-53.el5 or kernel-2.6.18-164.el5)

[Matti_Kurkela · Accepted solution]

Yes, that's probably enough to get rid of your problem.

The powernow-k8 module is included in the standard kernel packages, so updating the kernel updates powernow-k8 too.
