Resource 0 is not right and will not work.  In this case your BIOS has a buggy 
SMBIOS / DMI table entry for IPMI.

You can ignore the ipmi1 messages.

Are you sure you have working IPMI?  The timeouts and the busted DMI table
is consistent with a machine where IPMI is available via an optional
daughterboard, but the daughterboard isn't installed.
