I just tried that and there is still no output. I have append="rd.lvm.lv=maroon/usr console=uart,mmio,0xf8050000" in elilo.conf (and confirmed that it got installed that way in \EFI\gentoo\elilo.conf). In a test with 3.12.7-gentoo compiled with gcc-4.5.4, I could see the commandline being seen this way by the kernel. The same version, cleaned, rebuilt with gcc-4.7.3, does not output anything at all and reboots after a few seconds. --Dennis
