[PROBLEM] not booting anymore (switching to root)

[mindless]

Hi,

I successfully installed Xbian on my Pi2 since about a month now and everything was finally running smoothly, but a few days ago, I rebooted to test init scripts and the system could boot anymore.

It stays stuck on Switching to root and sometimes passes one step further (setting up x socket directories ...)

not relevant anymore (Click to View)

I changed my command line with "init=/bin/bash" but never went that far so I suspect a btrfs problem.

I tried to run btrfsck on a new ubuntu desktop install (14.04) but it keeps displaying the following error when trying to do anyhting with btrfs : Couldn't open because of unsupported option features (10).

I reckon it has something to do with the btrfs version i'm using and tried to compile the latest sources of btrfs-tools but the install didn't work, I updated to version 3.14 wih an ubuntu package but the problem is the same.

EDIT :
I just tried to add rescue_early to the cmdline.txt and i was able to get a shell.
The btrfs partition was mounted already and i was able to do "chroot /rootfs" where I could find all my usual files.
I ran btrfs check on the unmounted partition and it found no error.

I guess all this means that my filesystem is fine but I'm still stuck on swithching root during the boot process.


Can someone help me fix this ?

Thanks,
Regards.
