Thank you, I have found the problem, my sound card is Ensoniq ES1371 so the module should be snd_ens1371 but I used to load by mistake snd_ens1370 so I got the OOPS all the time, I fixed the alsa-config and now all works.

Please try snd_ens1370 with the patch Andrew posted and see if it still
oopses.  We need to know if it fixes the problem you are having, even if you
were using the wrong driver for your hardware.

No further testing is needed thanks.  Both bugs have been found.
