[arch-general] Kernel panic at boot after hard reset: not syncing. No init found.

[Paul Hervot]

Hello, I know some people had this problem before but no solution seems
to help me.

I was playing Kerbal Space Program, the game filled up my RAM, my
computer was no longer responding (it happens to me a few times a month
if I forgot to close firefox before playing for example).  I had to hard
shutdown, then on the boot I get this kernel panic.
(Here is a screenshot: http://dettorer.net/kernel_panic.jpg)

The init= parameter given by grub is correct: /usr/lib/systemd/systemd
and I double checked the root= parameter, it is by uuid but I also tried
by device name (/dev/sda7) and by label.
I use three partitions:
sda5: /boot
(sda6: swap)
sda7: /
sda8: /home
`fdisk -l /dev/sda` http://paste.awesom.eu/ux8
`ls -l /dev/disk/by-uuid` http://paste.awesom.eu/85U
Using the output of a new `grub-mkconfig` didn't fix it either.
Here is my grub.cfg: http://paste.awesom.eu/aDR

I tried running `mkinitcpio -v -p linux` (I use the 3.8 kernel from core
but also tried the 3.9 from testing, same result)
Here is my mkinitcpio.conf: http://paste.awesom.eu/yVH
and the output of `mkinitcpio -v -p linux` http://paste.awesom.eu/6f3

I checked the filesystems of my / and /boot partitions with badblocks
and fsck, no problem from here. (I also tried reformating my swap with
mkswap as the second line of kernel panic mention swapper even though I
didn't understand that line, I just gave it a try).

I don't know what to do now, my guess is that the initramfs can't
mount the root partition but the root= parameter is correct and
everything mount well under a liveCD (this is from where I try to fix
it).

PS: It's my first post on arch-general, sorry if my question is
off-topic or poorly presented.
