2015-07-28 08:26:07 penalvch summary Kernel panic - not syncing (clean 15.10 install) Kernel panic - not syncing
2015-07-28 08:26:16 penalvch description 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?
