[parisc-linux] Help with 710 Network Driver

[Richard Hirst]

Hi,
  I have looked at this a bit (remotely, I don't have a 710), and my
conclusion is that both scsi and lan drivers are talking to the
chips just fine.  The problem seems to be that the drivers never
receive interrupts from the chips, which probably means that the
interrupt routing needs setting up differently on these old machines.
Unfortunately I don't have access to any relevant documentation.
