Ok... We will try to enable debug on slab! :) Ring buffer full occurs on tx in spite of having free bd's in the ring, it doesn't use them... And it does not recover. The problems that I refered are from previous kernel versions to ours (our base of development was 2.4.31) and even on 2.6 kernels.

Hello! Thank you for replying! It't quite dificult to say if the problem exists without our changes, since the all software is dependent on this changes so to work with the hardware. I can't answer to that right now on that, but I forgot to add one thing: we have ring buffer ful
