Comment 54 for bug 477169

I installed ubuntu 9.10 1 week ago on my laptop using the windows installer Wubi.
It was a fresh installation (not an upgrade of a preexisting ubuntu system)
Everything went perfectly well.
I haven't changed any settings nor repository regarding software source lists or updates.
On tuesday 17 nov. I ran the update utility through the GUI to download and install updates. As far as I can remember, by default, in Ubuntu, default settings make that only security and recommended updates are downloaded.

Download and installation of updates went perfectly well. I normally shut down my laptop after that.

After that I didn't use my laptop until yesterday evening. At the boot screen, after selecting Ubuntu (the other entry is Windows Vista Home Basic), I ran into the kernel panic error message : Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,2)
