Bug 76513 – linux-kernel-2.6 output to one console only

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description KiR 2005-01-03 05:58:10 UTC]

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. CONFIG_VT_CONSOLE=y
CONFIG_HW_CONSOLE=y
CONFIG_INOTIFY=y
# CONFIG_SERIAL_NONSTANDARD is not set
CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_8250_NR_UARTS=4
CONFIG_SERIAL_8250_EXTENDED=y
# CONFIG_SERIAL_8250_MANY_PORTS is not set
# CONFIG_SERIAL_8250_SHARE_IRQ is not set
CONFIG_SERIAL_8250_DETECT_IRQ=y
# CONFIG_SERIAL_8250_MULTIPORT is not set
# CONFIG_SERIAL_8250_RSA is not set
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_UNIX98_PTYS=y
# CONFIG_LEGACY_PTYS is not set
3. add to boot loader (GRUB) console=tty0 console=ttyS1,19200n8

Actual Results:  
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.


Expected Results:  
Simply kernel must output to tty0 and ttyS1

Does it help if you make ttyS1 the first arg? e.g.

console=ttyS1,19200n8 console=tty0
