this one fixed it for me…

Hi
I just updated my fog server to the latest version using git

after upgrading, i can not register hosts…

the error is: kernel panic not syncing vfs unable to mount root fs on unknown-block(1,0)

I tried all the solutions posted before… but none of theme are working…

I uninstalled the fog, installed it again… same error, I updated the kernels, used older versions, same error…
I don’t know what to do else!
please help…

thanks
