Hi

I just installed gentoo on a new computer (kernel-genkernel-x86_64-2.6.39-gentoo-r3)
The installation worked well, but i was surprised that when i rebooted the machine,
the familiar messages didn't appear. The screen seemed to freeze with a message about "Booting the kernel"

Is there a way to get these messages back?

Thank You
Jody

What I can think of:

There is one option in 'Kernel Hacking' for boot messages in the kernel config.
Another way is to use the 'quiet' kernel command line, which suppresses boot messages.

But the system works just fine afterwards? i.e. you do see OpenRC starting and you do get a bash prompt or X?

@aquous: yes, after a pause of 20 seconds, the login prompt appears and everything seems to be working normal.

@disi: When i do search .config for "boot", i get
Code:
~ # fgrep BOOT /usr/src/linux/.config
CONFIG_NO_BOOTMEM=y
# CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS is not set
# CONFIG_IP_PNP_BOOTP is not set
# CONFIG_ISCSI_BOOT_SYSFS is not set
CONFIG_FB_BOOT_VESA_SUPPORT=y
# CONFIG_BOOT_PRINTK_DELAY is not set
CONFIG_X86_VERBOSE_BOOTUP=y

So to me it looks like it actually *should* talk during the boot...

About the " 'quiet' kernel command line"- where would that be?
It is not in grub.conf:
Code:
 ~ # cat /boot/grub/grub.conf

default 0
timeout 3
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title Gentoo Linux 2.6.39-r3
root (hd0,0)
kernel /boot/kernel-genkernel-x86_64-2.6.39-gentoo-r3 root=/dev/ram0 real_root=/dev/sda3 resume=/dev/sda2
initrd /boot/initramfs-genkernel-x86_64-2.6.39-gentoo-r3


Thank You
Jody

Looks fine to me... it would be in the line with resume and stuff

About the resume...
Do you actual shut down or hibernate/suspend to RAM?

Try:
Code:

# pm-suspend

and see if it looks the same?

//edit: or change it for testing to
Code:
noresume   

noresume [SWSUSP] Disables resume and restores original swapspace.

Hi disi

The boot messages were missing at the first reboot after gentoo installation,
and they also are missing after normal shutdown or after hibernation (which works perfectly).
