Found one thing that changed - compiler from 6.2.0-9 to 6.2.1-5 and 
binutils too in debian unstable (explicitly upgraded to get fix to the 
binutils bug that broke 64-bit kernels).

Well, the dmesg is not too verbose but when I debugged some earlier 
problem, netconsole and many other debugging options were left on.
