[gentoo-user] kernel bug?

[gentoo-user] kernel bug?

[Gmail]

Hi, i've upgraded kernel from 3.12.13 to 3.12.20.
I've make a oldconfig as usual, but with new kernel the boot blocks at 
the begining to the ramdisk loading.
I've tried with other 3.12.2x with the same negative results.
I use grub2 with systemd.

Maybe you should check your grub2 chkconfig whether 
it is OK, especially the "real_init"  filed.
Suggest if failed again, re-emerge dbus and systemd???

I've checked all many times...
The problem is present again

Anybody has the same problem with kernel 3.12.2x?

Is your '/usr' partition housed on a filesystem of its own, or does it
reside on the '/' partition?

http://wiki.gentoo.org/wiki/Initramfs/HOWTO
"For systems where all necessary files and tools reside on the same file
system, the |init| application can perfectly control the further boot
process. But when multiple file systems are defined (or more exotic
installations are done), this might become a bit more tricky:

  * When the /usr partition is on a separate file system, tools and
    drivers that have files stored within /usr cannot be used unless
    /usr is available. If those tools are needed to make /usr available,
    then we cannot boot up the system.

  * If the root file system is encrypted, then the Linux kernel will not
    be able to find the |init| application, resulting in an unbootable
    system.

The solution for this problem has since long been to use an /initrd/
(initial root device)."

Did you run a diff on your 3.12.13/.config and 3.12.13/.config, to make
sure you didn't overlook anything to do with the systemd-related config
options?

My /usr partition in on the / partition.

I just use initrd, i've compiled kernel with genkernel.

I'm trying to look row for row if there's some diff.

Googling for 'gentoo linux kernel gets stuck at ramdisk loading',
returned the following gentoo specific results. See if that helps pin

Did the output you got when generating 'grub.cfg' look similar to this?
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?style=printable&full=1#genkernel

Code Listing 2.3: Generating GRUB2 configuration

# grub2-mkconfig -o /boot/grub/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.12.20-gentoo
Found initrd image: /boot/initramfs-genkernel-x86-3.12.20-gentoo
done

The output of the command must mention that at least one Linux image is
found, as those are needed to boot the system. If you use initramfs or
used genkernel to build the kernel, the correct initrd image should be
detected as well. If this is not the case, go to /boot and check the
contents using the ls command. If the files are indeed missing, go back
to the kernel configuration and installation instructions.

Maybe you doesn't have enabled systemd support .

Are you using genkernel also to generate a the initramfs? for booting
systemd this is not supported by genkernel(tthat's is pointed in the
systemd instalation guide in the wiki), you should be using either
sys-kernel/genkernel-next, or sys-kernel/dracut(this has been the most
widely recommended on this list).

Yes, genkernel-next should be used. look at the install gentoo gnome with systemd from 
scratch ( Sorry for currently I can not access Internet so can not provide your link)
I have test genkernel-next with systemd (needed by GNOME 3.12)， all seems OK, with
kernel version 3.15。
But now I am using KDE 4.13 with openRC on ZFS。systemd sometimes makes things 
strange, I switched to KDE, all seems well currently.

I start to use genkernel-next from the upgrade to gnome 3.12 with systemd.

I must repeat: with kernel 3.12.13 no problem, with 3.12.2x kernel 
system block during the ramdisk loading.

I see many discussion about this problem (many without solution again), 
but nothing to solve.

Gentoo Bugzilla ask to me a dmseg where to see the problem's details, 
but when the system freeze don't make any dmesg output.
