Public bug reported:
I've just installed Kubuntu 15.10 and was able to boot into it once and
update the kernel. Since then, everytime I try to boot into it I get the
following error message:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-
block(0,0)
There might be other error messages before but I cannot see them as they
pass too fast, and the only messages I see are those shown in the
attached picture.
After some trial and error, I've discovered that this bug occurs when
booting with the quiet option. When I remove it, the kernel boots fine
most of the time (not everytime, but it's a definite improvement).
What's happening and how do I prevent it?
