Ah, I thought that could be so, I got confused.

Pity... everything seems correct, but something must not be so - we are
not progressing much.

Memory errors? Once I got a corruptions because I had to reseat my memory
chip. Run the memory check program from grub.

I also keep two systems on the same machine, one 8.2 and the emergency one
is 7.3. Same thing.

There wouldn't show much, because that partition is not mounted at the
time of your problems.

What are the messages you see before the last one (VFS...)? There might be
a clue.

Did you say the failsafe option from grub worked? If you have reinstalled
the kernel, both vmlinuz.shipped and vmlinuz are identical. In that
case, it must be a boot option it doesn't like...

Copy vmlinuz.shipped over vmlinuz, and initrd.shipped over initrd

Another idea: Use the failsafe boot, and remove options till it stops
