aid about kernel release

aid about kernel release

[sofia.munozvelez]

Hi,

I am  working with ESX servers at "Telefonica", located in Spain , Madrid.
And staring into the file /var/log/dmesg I have already found the following
message several times:
"An unexpected IO-APIC was lound.If this kernel release is less than three
months old please report this to linux-smp@vger.kernel.org".

The version of the ESX is 3.02, and the ouput of "uname -a" is :      Linux
esxc03s01.vmware.adm 2.4.21-47.0.1.ELvmnix #1 Mon Nov 19 18:30:34 PST 2007
i868 i868 i286 GNU/Linux

The vmkernel version is "63195"


Could you tell me what´s wrong or which outputs do you need furthermore?
Should we upgrade the linux version?

Thanks in advanced.

2.4.21 is from June 13, 2003, over 4 year old. The "-47.0.1.ELvmnix"
string suggests it's a vendor kernel.

There's nothing wrong, the kernel just tells you it doesn't know the
IO-APIC and tries to work with it. The warning is not uncommon for old
kernels running on modern hardware.

If everything works like it should, you don't have to upgrade (minus
security updates, but it is very well possible your vendor takes care
about that).
