re-reproduction avec cette pile d'appel là :

ipintr(58,10,10,10,d08c6000) at ipintr+0x70
Bad frame pointer 0xd08c7e14

je vais voir ce que ça donne en changeant une carte reseau.
Mais ça va être dur de toutes les changer, yen a 4 dans la machine :(

sinon pour ceux qui s'y connaissent, y a t il moyen de changer mon kernel
de 4.2 en un kernel 4.1 sans devoir tout réinstaller ?

merci d'avance.
