I recently had to reformat my sd card for my pi as I was getting an error (below), no idea what had caused this error but reformatting fixed it.
kernel panic not syncing: VFS: Unable to mount root fs on unknown-block 179,6
Now I am having a new issue when booting, probably around 50% of the time. When booting it sometimes hangs on:
waiting for /dev to fully populate
Or words to that effect. Following this it seems to cycle, very quickly, through some code that keeps throwing up errors and never boots. The only way I can fix it is by pulling the plug (I know, bad practice, but I can't get it to stop any other way).
Any ideas what could be causing this and how I can stop it?
FYI. I am using a mobile phone charger to power the pi and always have, never had this issue prior to formatting the sd card.
