타겟 보드에서 랜드라이버가 올라가는 도중 문제가 발생합니다.

이주째 삽질을 하다가 여러 분들의 조언을 듣고자 이렇게 글을 올립니다.
보드의 간단한 사양은 amd au1200 이고 랜은 smsc lan91c111-ne입니다.
커널에서 랜을 올리는데 문제가 발생 하는데 원인을 모르겠습니다.
제가 실시간으로 확인 중이니 조언좀 부탁드립니다.

아래 문제되는 소스는 Smc91111.c 입니다.
static int smc_wait_to_send_packet( struct sk_buff * skb, struct net_device * dev )
{
struct smc_local *lp = (struct smc_local *)dev->priv;
unsigned int ioaddr = dev->base_addr;
word length;
unsigned short numPages;
word time_out;
word status;

PRINTK3("%s:smc_wait_to_send_packet\n", dev->name);
udelay(200);

if ( lp->saved_skb) {
/* THIS SHOULD NEVER HAPPEN. */
lp->stats.tx_aborted_errors++;
printk("%s: Bad Craziness - sent packet while busy.\n",
dev->name); //이부분에서 계속 루프를 도네요....원인두 모르겠고...ㅠㅠ
return 1;
}
lp->saved_skb = skb;

로고를 간단하게 올리면......
