Cant update kernel (strange)

kopiersperre · 2015-02-09 15:27:00

Dear community,

uname shows 3.18.1 – whatever which kernel version is really installed. I haven't reboted the notebook for several weeks. Now its indifferent wether I update to 3.18.5 or 3.18.6 – uname does not change.

At the moment I am working with 3.18.1 because there are no drivers, when I update to 3.18.6 and reboot.

/boot is writable

ls -l /boot:

-rw-r--r-- 1 root root 27785816  9. Feb 16:05 initramfs-linux-fallback.img
-rw-r--r-- 1 root root  6430511  9. Feb 16:05 initramfs-linux.img

-rw-r--r-- 1 root root  4062816 17. Dez 15:41 vmlinuz-linux

mkinitcpio runs

no drivers, no internet, no nouveau
nothing works

Where does this strange problem come from? May you help me?

Do you have a dedicated boot partition? Is it mounted?

OR

Are you booting in EFI mode? Is the kernel + initrd copied into the right place for the boot manager to load it?

Do you mean you're not rebooting after installing the new kernel?

kopiersperre · 2015-02-09 16:02:04

I noticed this problem after not rebooting for a long time. So now I have rebooted many times.

sudo efibootmgr:

That doesn't tell us anything other than you are using EFI to boot.

What is "EFI HDD Device (ST1000LM024 HN-M101MBB)"? Is the ESP mounted anywhere? How do you transfer the kernel and initrd to it? (e.g. https://wiki.archlinux.org/index.php/EF … unt_Points)

kopiersperre · 2015-02-09 16:32:02

I just use pacman. After updating the files in /boot have a newer date than before.

It's an EFI notebook, but I've used the most non-EFI mode at installation.

Let me put it this way: When you upgraded the kernel, did you reboot the machine?

1) If you upgraded the kernel and did not reboot the machine ever, then this is expected because you're in a session with the kernel you booted up in, not the upgraded one.

2) If you upgraded the kernel and did reboot the machine, then we need to work out what is up with /boot.

3) If you are doing some kind of dynamic loading of new kernels without re-booting, then please tell us what you're doing.

Which one of these are you?

EDIT: I was debating asking whether you should post the output of the uptime command as well, to help convince me whether your machine has been up since you last booted up 3.18.1. I'll leave that to your judgement.

I think you are wrong, and are in fact using EFI mode. I come to this conclusion because you have posted output from efibootmgr. Efibootmgr only displays the list if you are booted in EFI mode.
It is very likely that you have not copied the new kernel files to the EFI system partition.

kopiersperre · 2015-02-09 19:31:35

You're right, I have EFI. (2) applies to me.

With GParted I could figure out my problem. EFISYS partition is not mounted.

sudo mount /dev/sda2 /boot

fails:

dmesg:

How did you install Arch?

kopiersperre · 2015-02-09 20:07:55

with archboot

jasonwryan · 2015-02-09 20:16:31

So, you aren't sure whether or not you are booting MBR or EFI? Your boot/ESP is on sda2 but that isn't in your /etc/fstab and the entries that are in there, including an EFISYS partition, are all commented out?

It is a miracle you can boot at all...

The error about the codepage is not the source of the problem, but a symptom of it. The kernel needs a module to access FAT file systems. Loading the module is not possible because the modules found on your system are not compatible with the kernel you are booted into.
Use the archboot usb stick or any linux live cd to copy the new kernel onto the EFI partition. Then you can boot into the new kernel, and mount the FAT file system, which allows you to fix all of your problems from within arch.

Ok, downgrading linux-headers with Arch Rollback Machine, mounting /dev/sda2 to /boot and then updating the kernel fixed my problem.

Thanks for advices. SOLVED.

teateawhy · 2015-02-10 16:09:03

Are you sure that you have made the necessary configuration so that this will not happen again after the next kernel update?

kopiersperre · 2015-02-11 09:45:33

No. But I know EFISTUB/ArchWiki.
