I have a 2.6.32 kernel running on two different machines.
The init messages look different and I'm not sure why.

Machine A:
IPMI System Interface driver.
ipmi_si: Adding SMBIOS-specified kcs state machine
ipmi_si: Trying SMBIOS-specified kcs state machine at i/o address 0xca8, slave 
address 0x20, irq 0
ipmi: Found new BMC (man_id: 0x0019fd,  prod_id: 0x19e7, dev_id: 0x20)
IPMI kcs interface initialized
IPMI Watchdog: driver initialized
ipmi device interface


Machine B:
IPMI System Interface driver.
ipmi_si: Adding SMBIOS-specified kcs state machine
ipmi_si: Adding ACPI-specified kcs state machine
ipmi_si: Trying SMBIOS-specified kcs state machine at mem address 0x0, slave 
<== address 0x0 ?
address 0x20, irq 0
Could not set up I/O space
ipmi_si: Trying ACPI-specified kcs state machine at i/o address 0xca2, slave
address 0x0, irq 0
ipmi: Found new BMC (man_id: 0x0019fd,  prod_id: 0x1ee6, dev_id: 0x20)
IPMI kcs interface initialized
IPMI Watchdog: driver initialized

So what is the reason SMBIOS failed on machine B? The SMBIOS messages 
themselves are different between the two machines.

Do SMBIOS and ACPI both exist in the BIOS at the same time?

Thanks.

Dave
