Mine is com1=115200,8n1,0xff5e0000,0

The smaller numbers are for legacy compatible serial ports
(e.g. Intel Tiger) and the larger numbers are for non-legacy
boxes (e.g. HP).

Look for a value like 0xff5e0000 when booting native
Linux near the boot time output where Linux is initializing
the console.

I believe the problem occurs because EFI is configured with two
output consoles (VGA and serial).
