The 'No such device' error is occurring because you are trying to load the module, and 'modprobe' is finding the kernel module, but when it loads, the kernel module is unable to discover the hardware, so it fails. Look at the output of 'dmesg' to see if there's any output related to loading the module. ipmi_si has several parameters you can specify which can increase debugging. It looks to me like your hardware doesn't have a BMC that supports IPMI. Have you verified that the hardware you bought has one? Can you get into the BIOS and set it up that way? -- Jonathan Billings <billings at negate.org>
