<div>Hi, </div>
<div> </div>
<div>My target board is similar to Tyan s2882, I base on s2882's code to fit my target board.</div>
<div> </div>
<div>My target board also got an onboard Intel 10/100 NIC, and I assign the irq like s2882 done.</div>
<div> printk_debug("setting Onboard Intel NIC\n");<br> static const unsigned char slotIrqs_8111_1_8[4] = { 9, 0, 0, 0 };<br> pci_assign_irqs(bus_8111_1, 4, slotIrqs_8111_1_8);<br> write_pirq_info(pirq_info, bus_8111_1,(4<<3)|0, 0x1, 0xdef8, 0, 0, 0, 0, 0, 0, 0, 0);
<br> pirq_info++; slot_num++;<br> </div>
<div>It can works fine on unique processor platform, but when I boot into smp kernel it's interrupts is not going.</div>
<div> </div>

<div>Is it possible cause by IO-APIC ??</div>
<div> </div>
<div> </div>
<div> </div>
<div>The other question, my VGA still has snow screen when linuxbios booting,</div>
<div>
<div>even I moved the CPU init before other pci device init call.</div>
<div>But after I login the system, it will become clear. </div></div>
<div>following is part of my log....</div>
