[SOLVED] System froze and won't boot.

When I pluged in my power adapter on my laptop my entire system froze and forced me to cut the power.

Now when I try to boot it I get several errors about mounting and udev and more which I can't catch in the speed. Then it enters a long loop of printing

systemd[1]: Failed to start Journal Service.

And finally prints:

systemd[1]: Failed to start Journal Service.
systemd[1]: Failed to start Emergency Shell.
systemd[1]: Dependency failed for Emergency Mode.

Now only thing I can do is reboot, with the same result. I have no clue what to do so now I reach out for help here.

Thanks in advance.

Re: [SOLVED] System froze and won't boot.

I'd run the live cd and see if the partitions still mount as a start.

Partitions mounts just fine on live usb. I was also able to read the journals from before the crash but couldn't find anything I thought was usefull. Neither btrfsck gave me anything.

I've been able to catch more errors:

[FAILED] Failed to mount Huge Page File System.
[FAILED] Failed to mount POSIX Message Queue File System.
[FAILED] Failed to start udev Coldplug all Device.
[FAILED] Failed to mount Debug File System.
[FAILED] Failed to start udev Kernel Device Manager.
[FAILED] Failed to start Remount Root and Kernel File System.
[FAILED] Failed to start udev Kernel Device Manager.
[FAILED] Failed to mount /tmp.
[DEPEND] Dependency failed for Local File System.

Guess I should mention that I use [testing].

Re: [SOLVED] System froze and won't boot.

Kernel 3.7.0 + laptop-mode-tools are freezing the laptop when switching from battery to A/C.

As a workaround uninstall laptop-mode-tools until problem is fixed.

Indeed this was the cause.

Anyway I've manage to solve it, here is the steps:

1) Boot a live cd

2) Set up and enter a chroot according to https://bbs.archlinux.org/viewtopic.php?id=154625

3) Disable [testing] from /etc/pacman.conf

4) Run:

pacman -Syyf util-linux
pacman -Syyf linux linux-headers

I got som wierd errors at first which was gone after reinstalled util-linux.
And to get rid of the cause:

pacman -R laptop-mode-tools

5) Although this did not really work out so I did:

mkinitcpio -p linux

6) Exit chroot and reboot.

Maybe not all of those cammands are needed but that's how I solved my problem(s).
