Thanks!This patch can fix the issue.

>The only inialization linuxbios would need to do is assign the 8139 an
>IRQ. But etherboot uses polling and doesn't depend on interrupts.
>The problem you're experiencing isn't something I can recall, but this
>patch might help. The etherboot driver for the 8139 and linux itself have
>the meaning of the interrupt status bits wrong.
