Hi,
thank you all for reporting this change.
As already stated in bug #12893 - thanks, @chrisk1 -, this change has been intentionally conducted by the kernel developers. It is nothing to worry about (quite the opposite, actually), and at IPFire, there is nothing we can do.
Since the entropy graph does not display any valuable information with this new kernel (it always shows 256 bytes of entropy are available), I will remove it entirely, to avoid additional confusion.
Thanks, and best regards,
Peter Müller
