there is nothing to fix, it's the normal information that the kernel is sending you.
do you have a usb-drive, sd-card attached to the computer at boot?
if you do this is normal behaviour;
you see, regular HDD have an onboard memory that acts as buffer for optimization; that memory is not present is in usb-drives and sd-cards.
one of the things the kernel checks is the existence of that memory to define the way it should communicate with those devices;
usually you should see a second message
Code: Select all
assuming drive cache. write through
the kernel defined the method it is going to use to write to that/those devices.
