Hello.

Thank you, Martin.
Yes, now linux can detect the scsi contoller with your patch. But the
scsi driver cannot find the connected hard drives.

I tested a little more and find that the problem doesn't appear under
the kernel of uni-processer and traditional interrupt contoller.
It seems io-apic bothers pci or scsi. But, with my ugly patch,
everything is fine whether the kernel is for uni- or multi-processors,
for io-apic or xt-pic.

Yes, I will send you later in another mail since it is a little
larger.
