None of this has changed as far as I can see? 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). > Is it just timing and the transmit queue being busy? Perhaps due to the sheer size of messages? Meelis does seem to have a ton of debugging enabled.. Well, the dmesg is not too verbose but when I debugged some earlier problem, netconsole and many other debugging options were left on. -- Meelis Roos (mroos@linux.ee)
