Subject: Re: [NS] page allocation failure. order:2, mode:0x204020 while enabling Jumbo frame

Bom dia,

É pena que o título não tivesse começado por "bnx2x: ".
Não acredito que este problema seja transversal a todas à as placas de rede.
Brevemente teremos oportunidade de testar uma placa diferente, que vai sair de uma das brites.
