[PROBLEM] Xbian is corrupted upon reboot

[johnchristopher]

I think I figured the problem(s) out:
- PSU wasn't delivering enough power (cheap dual usb charger 5v-1.0A) ;
- unplugging the pi too many times without properly shutting it down.

Somehow I managed to fix the "freeze after shutting down" problem by ssh'ing into the pi and shutting down manually a few times. Now the shutdown button seems to always work.

I tried another USB charger that I found in my stash. 5V-1.5A. The LEDs are much brighter now

Haven't noticed any corruption since then. I will have to wait a few days to confirm it now works.

@Koenkk:
Will try that if corruption still occurs in few days.

@namtih:
Nice trick there. I didn't know anything about ext4 syncing. At some point I thought of disabling journaling. Will try that if corruption happens again in a few days.

Thank you all!
