When using gentoo-dev-sources, genkernel (i.e. initrd) and more than one console (like this 'kernel ... udev console=tty0 console=ttyS1,19200n8') output stops to tty0 after initrd /linuxrc starts (??? last message on tty0 is 'Freeing unused kernel memory:...'). With linux-kernel-2.4 it works fine. For 2.6 i use udev, genkernel --udev. Reproducible: Always Steps to Reproduce: 1.genkernel --udev --install 2.

With linux-kernel-2.4 it works fine. For 2.6 i use udev, genkernel --udev. Expected Results: Simply kernel must output to tty0 and ttyS1 motherboard: SE7501WV2SCSI Portage 2.0.51-r3 (default-linux/x86/2004.3, gcc-3.3.4, glibc-2.3.4.20040808-r1, 2.6.9-gentoo-r13 i686) ================================================================= System uname: 2.6.9-gentoo-r13 i686 Intel(R) Xeon(TM) CPU 2.66GHz Gentoo Base System version 1.4.16 ccache version 2.3 [enabled] Autoconf: sys-devel/autoconf-2.59-r5 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.15.90.0.1.1-r3 Headers: sys-kernel/linux26-headers-2.6.8.1-r1 Libtools: sys-devel/libtool-1.5.2-r7 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O2 -mcpu=i686 -fomit-frame-pointer" CHOST="i386-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/share/config /var/bind /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -mcpu=i686 -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://gentoo.osuosl.org http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://server.home/portage" USE="x86 accounting acl apache2 berkdb bitmap-fonts crypt cups encode expat ext-png ext-zlib foomaticdb fortran gdbm gif imap ipv6 jpeg libwww lua mad md5sum mmx mpeg mysql ncurses nls nptl oggvorbis oss pam perl png pthreads python readline sasl sdl serial slang ssl tcpd tiff xml2 zlib"
Does it help if you make ttyS1 the first arg? e.g. console=ttyS1,19200n8 console=tty0
