[SOLVED] Upgrading kernel mess with the system

Hi All,

I have recently installed Arch x86_64 on my new laptop. Everything works fine, except when I upgrade the kernel.
Running "pacman -S linux" seems to be fine, it executes mkinitcpio and create new kernel images. The system boots, but it behave very strangely. Xorg starts fine, but keyboard and touchpad doesn't work. In KDE on system tray some icons (like kmixer) have a question mark instead of correct one. There's also no WiFi available. Attached USB mouse doesn't work.
If I disable KDM and boot to console then keyboard works, but still I can't use USB devices. The usbcore module is loaded, but USB devices don't work, eg. pendrive is detected as high-speed device, but it is not recognized as removable drive.

I have same issue on two different laptops I have installed Arch on recently (1st laptop is Compaq 6510b, Arch x86_64, kernel 3.11.6; 2nd laptop is Compaq M2015, Arch x86, kernel 3.12).
Both laptops were installed from same medium - a CD I have burned from .iso image. Both laptops installed according to Arch wiki.
For a moment I have blacklisted kernel package, but I would like to upgrade it.

Help, please

Run pacman -Syu.

Jason, pacman -Syu was the first thing I did.

The look through X's logs, dmesg and the journal to try and pinpoint what is causing the issue.

Re: [SOLVED] Upgrading kernel mess with the system

This must be the reason:

dmesg

[    0.000000] Initializing cgroup subsys cpuacct

core/linux 3.12.2-1 (base) [installed]
    The Linux kernel and modules
core/linux-headers 3.12.2-1 [installed]
    Header files and scripts for building modules for Linux kernel

Yes, I have a separate boot partition, but it is mounted.

Yes, I have a separate boot partition, but it is mounted.

Then this looks wrong:

BOOT_IMAGE=/boot/vmlinuz-linux

If /boot is a separate partition, the kernel from the bootloader's point of view is in /, not /boot

└» mount|grep /boot
/dev/md0 on /boot type ext2 (rw,relatime)
└» dmesg|grep "Command line: BOOT_IMAGE"
[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-linux root=UUID=a6336994-8c19-42f1-8e52-bbb0a7fdec27 ro rootflags=subvol=arch-root

So, your bootloader config is faulty.

Re: [SOLVED] Upgrading kernel mess with the system

Teekay, you're right.
My grub.cfg was messed up, I don't know why. Most probably I did something wrong during installation.

Removing unnecessary boot folder from root partition and running grub-mkconfig & grub-install solved a problem.
Case closed.
