By experience, some IPMI hardware implementations are not sufficient to ensure efficient reboot, for example, we had some issues rebooting the nodes when they were in the PXE boot stage, or blocked in grub with a missing kernel, or worse: when running a freeBSD system.
that is most peculiar - why would any activity on the host affect the IPMI in the first place? oh - was this IPMI one of the ones that shares a NIC/port with the host? I can easily imagine that would cause some possible issues.
Many other solutions are OK: they tend to be scriptable though a telnet + expect script, so it's OK as long as it can reboot all your nodes in any situation.
I guess I'd be surprised if the protocol to the BMC made any difference - IPMI or telnet. but I'm often surprised ;)
