Alpha SMP Beowulf cluster: problems with SMP and ethernet !!

Here is what I found trying with your driver.
1) if the driver is loaded inside the kernel the system hangs with the
ping command in SMP mode. All ok with no SMP kernel.
2) if the driver is loaded as module the same behaviour occurs as before.
BUT !!!!!! BUT if I stop the network (ifconfig gives nothing), rmmod
eepro100 and again insmod eepro100 and again start the network, everything
works fine !!! Same if I try with 3C905 (another driver of yours).

My conclusions are:
1) I wrote a simple script that does this at boot.
2) there is something wrong with allocation of interrupt in the alpha
kernel for ds264 boards.
3) I keep this bad patch until the problem goes away.
