Multiple computers.

[<fir...@se...>]

We are trying to connect multiple computers using firewire for a high
speed network, and are having a some problems with the driver.

When I load the driver on the first machine it can see all of the machines
on the network.  I used 'testlibraw' to check.  Now when I load the
drivers on the next machine 'testlibraw' reports that it is the only
machine on the network, but 'testlibraw' on the first machine now shows
comm between the two.  Then when I try to load the drivers on the next
machine, it has the same problem as the second machine, but now the second
machine can see all of the nodes on the network.  The keeps happening as I
load the drivers on other machines.

So is there a way to get the last machine to see all the computers on the
firewire network?

I am attaching the testlibraw output I got.

For some reason, the ohci driver sometimes doesn't work properly on the
first 'insmod' after hardware reboot... have you tried to load it again
a couple of times and see if things are improving ?

Well first off I am using the pcilynx driver, so I don't think that is the
problem.  I might have put down the wrong card in my previous email (could
not remember the exact card).  I did try your suggestion, but it did not
work, testlibraw still does not see any of the nodes on the network.

Thanks.
