The Bad block table is written once. When you see this message multiple
times then this means that Linux can't read the BBT and writes it again.
So the question is: Start the good kernel multiple times. Do you see
this message once or on each boot? Then start the bad Kernel multiple
times. Do you see the message once or on each boot?
