HI.
I accidentally deleted my beloved .config which I saved for a 8 last years, and now I have to restore it.
Unfortunately /proc/config.gz doesn't exist so I can't get it back in a simple way. If there is a way to restore it without /proc/config.gz please let me know.
Right now I have compiled and running 4.9.95 kernel.

Meanwhile I tried to restore it from scratches. I downloaded and installed previous kernel 4.9.76-r1 (just to prevent a mess with current 4.9.95 kernel), navigated to sources directory and run
Code:
make tinyconfig

It gave me a start point config, which I loaded with make menuconfig and tweaked it (added drivers, changed some settings etc).
I saved changes, exited and compiled kernel:
Code:
make && make install && make modules_install

I added grub menu entry
Code:
menuentry 'Gentoo GNU/Linux' {
   load_video
   insmod gzio
   insmod part_msdos
   insmod ext2
   set root='hd0,msdos2'
   linux   /boot/vmlinuz-4.9.76-gentoo-r1 root=/dev/sda2 ro
}

and rebooted. When I selecting this menuitem and pressing enter key nothing happenes. Kernel doesn't load, just black screen without any warnings or errors. Only blinking white cursor on a black screen
What am I missed? It's not a grub menu issue, menuentry identical to 4.9.95 kernel which works fine. It's a kernel issue.
Here is my new config: https://pastebin.com/dfR5uJw7

New config is noticeably smaller then old one: 56 kB vs 86 kB. As well as new kernel is smaller then old 4.9.95: 1.9 MB vs 3.5 Mb

Blind_Sniper,

We need the output from lspci so we can see your hardware.
the output from lsusb, with all your USB devices attached
and the output of
Code:
df -Th
so we can see your filesystems.

Does your system use BIOS or UEFI to boot?

If you want to have a go on your own, search the forums for Pappys Preconfigs.

-- edit --

You don't have any console drivers set in your kernel. That's not a problem for booting but your console is limited to black text on a black background. I've done that too. Its rather hard to read. :)

NeddySeagoon, thanks for your input.

My system uses legasy BIOS, new kernel I trying to build is located at the same /boot directory as my current bootable 4.9.95 kernel.

Code:
# df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/sda2      ext4       24G   19G  3.9G  84% /
devtmpfs       devtmpfs   10M     0   10M   0% /dev
tmpfs          tmpfs     796M  740K  796M   1% /run
shm            tmpfs     3.9G  2.8M  3.9G   1% /dev/shm
cgroup_root    tmpfs      10M     0   10M   0% /sys/fs/cgroup
tmpfs          tmpfs     6.0G     0  6.0G   0% /var/tmp/portage
none           tmpfs     3.9G  4.0K  3.9G   1% /run/user/1000


Code:
# lsusb

Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0000:0538

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub



I have only USB keyboard and USB mouse attached at the moment, no any other sticks or HDDs which could interfere to boot.

Thanks, I added CONFIG_VGA_CONSOLE option and rebuild kernel. Going to try it.

Added:
VGA_CONSOLE made no difference. The same black screen with a blinking white text cursor.

Blind_Sniper,

Post the rest of the information I asked for and I'll look at it tomorrow.

There is chance you have old configs stored in /boot
( I dont know on what it depends )

At quick look you miss SCSI disk support probably ( in device drivers, scsi dev support)

Thanks for reply, mir3x
I tried to enable SCSI disk support but it doesn't help.

But now I have it bootable: I enabled CONFIG_PRINTK to be able to see what is going on.
And added Intel ICH LPC support.
Now system boots but stops at login prompt. When I typing user name and password it just ignores it and asks for login over and over. Can't login neither as user nor as root.
But I can login as root in single user mode.

During the boot I see only one error message: "Call to flock failed"
Have no any Idea what it is. And how it's related to login problem


My current config : https://pastebin.com/AhcAaTqY

You have kernel seeds to use as base for your kernel config eg. there https://forums.gentoo.org/viewtopic-p-8122476-highlight-.html#8122476

You are missing something from device drivers -> character devices -> ( CONFIG_VT , CONFIG_UNIX98_PTYS, VT_CONSOLE maybe?)
EDIT: NVM, I see you have it enabled, maybe it's CONFIG_DEVMEM=y, try just those seeds,as a base, it will be easier.

Start with the config from the sysrescuecd, then use lspci, and so forth to tweak it?

I have all above kernel drivers built-in. I think it's no more relevant because I can boot now.

If I'd have such a backup I wouldn't post my question here.

This config (Pappys Config) doesn't boot at all (just kernel panic), I tried to use it "as is" and tried to combine with mine (Device drivers section) - no luck.
So right now my config at least boots. Seems it needs one or two options to be enabled.

Right now I'm getting some messages while booting, may be they are relevant to the login problem:

Code:

OK i quickly googled flock and found right answer
Its FILE_LOCKING (Enable File POSIX Locking API)

No idea about failed logins, lets hope its the same issue.

FILE_LOCKING doesn't help as well.

I scrolled kernel boot messages up (Shift+PageUp) and found some strange strings there:

Code:
This kernel doesn't have devtmpfs or tmpfs support, and there is no entry for /dev in fstab. This means /dev will not be mounted.
To avoid this message set CONFIG_DEVTMPFS or CONFIG_TMPFS to y in your kernel configuration.
...
...
...
...
CONFIG_DEVTMPFS=y is required in your kernel configuration file for this version of udev to run successfully


How can it be true, if I ran immediateley
cat .config |grep TMPFS
and got this output:

Code:
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y
CONFIG_TMPFS=y
# CONFIG_TMPFS_POSIX_ACL is not set
# CONFIG_TMPFS_XATTR is not set


what's wrong with DEVTMPFS?
Or is it udev issue?

I haven't looked over your entire config but did notice several items you may need to enable depending on what packages you are or will be using. You should enable
Code:
# CONFIG_TMPFS_POSIX_ACL is not set
"POSIX Access Control Lists (ACLs) support additional access rights for users and groups beyond the standard owner/group/world scheme, and this option selects support for ACLs specifically for tmpfs filesystems.

If you've selected TMPFS, it's possible that you'll also need this option as there are a number of Linux distros that require POSIX ACL support under /dev for certain features to work properly. For example, some distros need this feature for ALSA-related /dev files for sound to work properly. In short, if you're not sure, say Y."

You may also need
Code:
# CONFIG_TMPFS_XATTR is not set
Do you use pulseaudio? If so
Code:
CONFIG_SND_HDA_PREALLOC_SIZE=64
should be set to
Code:
CONFIG_SND_HDA_PREALLOC_SIZE=2048

One thing to keep in mind when checking the kernel's config for stuff, the .config file in the kernel's sources is NOT necessarily the same as the running kernel's config. This is especially easy to mix up, as you could very well be running a old kernel (often the /boot partition is not mounted by default), so it is easy to forget to make sure you mount that partition before you install the kernel. You should always check the output of uname -a and make sure you are running the intended kernel. That output will also tell you how many times the kernel was recompiled.

If you have the option set in the kernel (don't remember which one exactly right off hand), but you will have a config.gz file in your /proc which is the running kernel's config (very useful to know what the kernel is actual configured for).

I enabled CONFIG_TMPFS_XATTR and CONFIG_TMPFS_POSIX_ACL but it doesn't help

I have no separate /boot partition, and I build kernel named "vmlinuz" to be sure that there is no any mix up with other kernels (they has names like kernel-X.XX.XX-gentoo).
I start checking for config options via zcat /proc/config.gz, so I checking it on a running kernel.
Every time I boot I check kernel creation date and time (uname -a) as well as I check it when I copy compiled kernel to /boot directory.
So there is no any mix up.

I am reasonably sure you will need "CONFIG_TMPFS_POSIX_ACL". Also you have several items turned off that I generally have enabled, some of which I believe are related to some of your errors during boot. I suggest enabling them or at least read the documentation before you decide to enable or disable any kernel settings. Sometimes the docs don't say much that's when you enlist the help of google or additional documentation.
Code:
CONFIG_MULTIUSER is not set
CONFIG_SGETMASK_SYSCALL is not set
CONFIG_SYSFS_SYSCALL is not set
CONFIG_BASE_FULL is not set
CONFIG_FUTEX is not set
CONFIG_EPOLL is not set
CONFIG_SIGNALFD is not set
CONFIG_TIMERFD is not set
CONFIG_EVENTFD is not set
CONFIG_ADVISE_SYSCALLS is not set

This config (Pappys Config) doesn't boot at all (just kernel panic)

That would be very rare as I know he tests every seed before he releases them. They won't boot on your hardware until you configure them to do so. You would need to copy them into your kernel directory (if there is a .config there already remove it first) run
Code:
make silentoldconfig
after that is done run
Code:
make menuconfig
Then make sure all your hardware is set up, save the config, then run your make commands.

I would advise you read the Kernel Upgrade Guide and pay close attention to the section Solving Build Problems first before trying any of the options I have offered.

Restore it from a backup?
If I'd have such a backup I wouldn't post my question here.
You might if your backups were inconvenient to access (on tape, or stored off-site, ...) and you were hoping we had a more convenient method. ;)

Finally I recreated config by running make defconfig and using it as a base.
After a sequence of tweaks I got a kernel 4.5 Mb of size. It's a good start point to deal with kernel in future

Thanks all for your efforts, really appreciate it.
