Interupt infinite loop issue

Just glanced through my patch again, this comment may be relevant in my version of alt_sgdma_isr:

static inline void __alt_sgdma_isr(struct net_device *dev,
                                                                  struct alt_tse_private *tse_priv)
{
       tse_sgdma_disable_irq(tse_priv);
       
       if (napi_schedule_prep(&tse_priv->napi)) {
               if (netif_msg_intr(tse_priv))
                       printk(KERN_WARNING "%s: NAPI Starting\n", dev->name);
               
               __napi_schedule(&tse_priv->napi);
       } else {
               // BUG
               // if we get here, we received another irq while processing NAPI
               // this seems to happen when there is an rx interrupt and tx interrupt
               //  in short succession, but does no harm
               if (netif_msg_intr(tse_priv))
                       printk(KERN_WARNING "%s :TSE IRQ Received while IRQs disabled\n",
                                       dev->name);
       }
}
