Assuming you mean /var/log/messages and dmesg, they say nothing about SMIs except what I previously wrote.
I have managed to boot with SMI disabled in BIOS. The only trouble is I have to manually go into the BIOS bootloader and select to boot from USB every time or it reports there is no bootable device. It warns in the BIOS that disabling SMI will cause legacy USB boot to not work, so I presume this is the cause since my root fs is on a USB attached compact flash.
I will try now running tests with SMI disabled in the BIOS.
