Hello!
I am having an issue with how ESXi handles IPMI. The system process' vmklinux_9:ipmi_thread constantly utilizes a full CPU core. This bug seems to have been fixed in ESXi 5.5U1 (KB 2065824, PR 1075046). However, it now happens for me on version 6.0 build 3247720. As a workaround I tried disabling IPMI (setting VMkernel.boot.ipmiEnabled to false), yet after a reboot IPMI is still used for some reason. Motherboard and IPMI controller BIOS/firmware are latest versions.
Hardware configuration:
its good to open a ticket with VMware Support. May be the code fix in 5.5 is not cross ported to 6.0.
I can't figure out a way to do that. Apparently, there is no way to do so with a free vSphere Hypervisor license.
