The configuration change building ipmi_si into the kernel precludes the use of a custom driver that can utilize more than one KCS interface, multiple IPMBs, and more than one BMC. This capability is important for fault-tolerant systems. Even if the kernel option ipmi_si.trydefaults=0 is specified, ipmi_si discovers and claims one of the KCS interfaces on a Stratus server. The inability to now prevent the kernel from managing this device is a regression from previous kernels. The regression breaks a capability fault-tolerant vendors have relied upon. To support both ACPI opregion access and the need to avoid activation of ipmi_si on some platforms, we've added two new kernel options, ipmi_si.tryacpi and ipmi_si.trydmi be added to prevent ipmi_si from initializing when these options are set to 0 on the kernel command line. With these options at the default value of 1, ipmi_si init proceeds according to the kernel default.
