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@xxxxxxxxxxxxxxx". 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. Sofía Muñoz Vélez. Departamento de sistemas virtualizados.
