kernel panic after make install of fresh kernel compile

glennmcc · 09-15-2021, 12:49 PM

Houston, We have a problem.

I made a fresh compile of kernel 5.14.3

Luckily, was able to restore /boot from backup.

Here's what I found is happening after make install.

The problem looks to be with the new /boot/System.map

pghvlaans · 09-15-2021, 01:06 PM

Did the new kernel need an initrd? The one on the new list is still from September 12th.

marco70 · 09-15-2021, 02:08 PM

kernel-huge will rather boot without initrd.

Code:

menuentry 'Slackware64-15.0 GNU/Linux, with Linux 5.14.3' --class slackware64_15_0 --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-5.14.3-advanced-37937c0d-aa62-4a3c-8e12-9235e2d0e028' {
	load_video
	set gfxpayload=keep
	insmod gzio
	insmod part_gpt
	insmod ext2
	search --no-floppy --fs-uuid --set=root 37937c0d-aa62-4a3c-8e12-9235e2d0e028
	echo	'Ładowanie systemu Linux 5.14.3 ...'
	linux	/boot/vmlinuz-huge-5.14.3 root=/dev/nvme0n1p2 ro loglevel=3 quiet
}

Example from the grub.

Petri Kaukasoina · 09-15-2021, 02:23 PM

The size of your vmlinuz dated Sep 15 is so small that it's not huge. And the date of
initrd.gz is Sep 12 2020. Nothing uses System.map, but it seems ok. Its size is exactly the same as Slackware64-current has for System.map-generic-5.14.3 (smaller than System.map-huge-5.14.3).

Oh, jeez, I thought it was from a few days ago. Just what I get for not wearing my glasses.

marco70 · 09-15-2021, 02:35 PM

You are doing something wrong.
In the directory /usr/src/5.14.3/.config
comes with kernel-generic by default
You need to copy config from /boot/config-huge-5.14.3.x64 to /usr/src/5.14.3/.config

Make copies of your files before playing.

glennmcc · 09-15-2021, 03:28 PM

Step 1) copied /boot/config-huge-5.14.3.x64 to /usr/src/liunx-5.14.3/.config

Step 2) make menuconfig (did not make any changes, simply exited the menu)

Step 3) make

Step 4) make modules_install

Step 5) make install (lilo was automatically executed to update the boot loader)

Step 6) reboot

Result... kernel panic due to unable to mount root file system

Ah ha.... looking closer at the directory listing after make install....
looks like the symlinks are not being correctly created.

__________

Oh yeah, BTW.... all of this was done while logged-in as root...
not as a non-root user via su nor sudo

_____________

Well, well, well...

Looking at the contents of http://mirrors.kernel.org/slackware/...3-x86_64-1.txz

It does in-fact look like what got build and placed into /boot is in-fact the generic kernel.

This _should_ not be happening when what was used is /boot/config-huge-5.14.3.x64 copied to /usr/src/liunx-5.14.3/.config

Didier Spaier · 09-15-2021, 04:49 PM

Why not just run the scripts provided by Patrick Volkerding here?

glennmcc · 09-15-2021, 05:00 PM

OK.... just now done with the same step on my older setup to build a new 4.4.276 kernel.

As we see... it did in-fact result in a fresh build of the huge kernel.

The only thing it did not do was to create the symlinks to that fresh build.

glennmcc · 09-15-2021, 11:51 PM

Please accept my apologies for wasting everyone's time on this.

Started from scratch and it worked correctly this time
resulting in a fresh build of the huge kernel.
