Jut to make sure, you are rebooting the computer, not only restarting X after kernel up- or down-grading?

ATI open source (xf86-video-ati). But you are going in a wrong way, even if i try to boot without X, i stuck at missing wireless module. So the problem is (IMO), that system upgrades the kernel, but keeps looking for old (3.9.5) modules.

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

Do the modules in question originate from the repos or from the AUR?  If it's the latter, have you recompiled them for the 3.9.7 release?

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

It sounds like your /boot partition was not mounted when you did the upgrade.  /boot is usually a mount point on which your boot partition is mounted.  The new kernel and initrd are written to /boot during the upgrade.  If the boot partition is not mounted, then they files are written to the /boot directory, bit they never make it to your boot partition.

Are you using a separate boot partition?
Is it mounted?  (check the output of mount)
If it is not mounted, are there files in that boot directory?  (There should not be)
If it is mounted, unmount it and check to see if /boot is empty (if not, then it must not have been mounted at some time in the past)

Don't know how /boot (in unmounted state) was populated, but files are 10 days old. Anyway, i tried to upgrade to 3.9.6 second time few days ago, after unsuccessful result, a did pacman -U linux-3.9.5-1. Today after pacman -Suy, installing linux-3.9.7-1 & rebooting i stuck with the same troubles. So i did downgrade again to 3.9.5-1 (saving output first given in my first post)

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

Okay, it looks like /dev/sda1 is mounted as boot, and that is where your files are going; but...   There should be other files in the boot partition to support whichever boot loader you are using; there aren't. 

Could you post the output of sudo fdisk -l /dev/sda

That all looks reasonable (except for the ugly output of fdisk;  How did you create that?) 

But, your listing of /boot in post 11 makes no sense.  What bootloader are you using?

Syslinux.
First time i bought anything with UEFI and i hate it, after spending about 6 hours fighting against ~15 options for UEFI/Legacy(compatibility mode) in my BIOS and (and bloody UEFI), reading tons of manuals and wikis, reinstalling Arch, i think 5 times every time getting messages like "Theres no disk", "Theres no system to load" i really don't remember how managed to finally get a working system.

Unfortunately, I cannot help; I know nothing of UEFI and little of Syslinux.  I don't understand where you are booting from, but it is not looking in /dev/sda1 for the files you need.  Perhaps someone with UEFI and Syslinux experience could lend a hand here?

You gave me an idea) I upgraded kernel to version 3.9.7, copied everything to tmp folder, unmounted /boot and copied everything over /boot at /dev/sda (root partition), where was 10 days old kernel files, rebooted and now everything works fine. So now i'm lost how my boot proccess works.

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

Are you booting UEFI or BIOS legacy?

The output from fdisk looks odd. I take it you have a GPT partition map. If so, can you post gdisk -l /dev/sda? It is possible that the oddness is a quirk of fdisk's new support for GPT (I didn't even know it had this) and I would rather trust gdisk's output.

If I had to guess, I would guess the following: you are booting in legacy mode. The type code for your boot partition is incorrect.  Your boot partition was not mounted when you did the original install. In particular, it was not mounted when you installed syslinux. It is now getting mounted when you boot and is mounted when you upgrade. Hence, the upgraded kernel etc. end up on the boot partition but nothing else is there so you end up booting the older kernel from the boot directory. This was failing because the modules installed to / would not have matched the kernel in the boot directory.

One option would just be to get rid of the boot partition since it is working fine without it.

EDIT: If so, though, I am confused as I thought syslinux required the partition be marked as bootable but none of yours seem to be. However, I know little of syslinux. I am, however, confident you are not booting UEFI.

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

From the first look he's missing an EFI-Partition, I guess that's why he tried to use syslinux.

Easiest way to to a normal EFI-Layout would be, format sda1 as vfat, flag it as boot, mount it as /boot/efi, and then install grub-efi-x86_64 according to the wiki.

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

I moved to Syslinux because in one of my tries i installed Arch with Grub, but after reboot it stuck at "Grub loading" screen and i discovered Grub is needed some more packages or settings for GPT to work (i honestly don't remember), and i was fed up with all of this, so i simply reinstalled once more with Syslinux. Why i choose GPT? Arch installation guide says:

GUID Partition Table (GPT) is an alternative, contemporary partitioning style. It is intended to replace the old Master Boot Record (MBR) system. GPT has several advantages over MBR, which has quirks dating back to MS-DOS times. With recent developments to the formatting tools fdisk (MBR) and gdisk (GPT), it is equally easy to use GPT or MBR and get maximum performance.
The choice basically boils down to this:
If using GRUB legacy as the bootloader, one must use MBR.
To dual-boot with Windows, one must use MBR.
A special exception to this rule: dual-booting Windows 64-bit using UEFI instead of BIOS, one must use GPT.
If none of the above apply, choose freely between GPT and MBR. Since GPT is more modern, it is recommended in this case.

Is there any command like "grub-install" for Syslinux to simply reinstall it to /boot partition ?

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

EF02 legacy bios partiton.

And afaik grub-efi doesn't need extra packages.
Just an vfat partition with boot flag (or EF00 with gfdisk)

mkdir -p /boot/efi
mount -t vfat /dev/sdXY /boot/efi
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --boot-directory=/boot/efi/EFI --recheck
mkdir -p /boot/efi/EFI/grub/locale
cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo

after that it should work with grub (you may have to select arch_grub as default in the "bios" setup)

At least it always worked for me.....

Syslinux:
https://wiki.archlinux.org/index.php/sy … ic_Install

And if I read https://wiki.archlinux.org/index.php/syslinux correct it should use the kernel on the syslinux partition that was statet in syslinux.cfg

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

I reinstalled syslinux package (after making sure /boot is mounted on /dev/sda1), ran "syslinux-install_update" (from installation guide), set up syslinux.cfg (changed Menu Label to make sure which of configs is used during boot), and everything worked fine. Tested with downgrading to 3.9.6: after reboot "uname -r" and "pacman -Qi linux" showing same output.

Thanks everyone) will mark as solved.

Re: [Solved] Uname doesn't changes after linux-3.9.5 upgrade

The type code for your boot partition is incorrect. It is not a BIOS boot partition. You do not need one of those for syslinux and, if you did, it would not need a filesystem and would be much smaller (1-2MB). As far as I know, you would only use that with grub with GPT and bios booting.
