[eepro100] shared interrupt (irq)

Hi Christoph,
Thanks for early reply.

There is no one error message for hangs. It looks as searching for IP 
address at reboot time and freezes, while it has a static IP address.

There is no NFS configured in the machine even.

The EEPRO100 devices are shareable with the pci Line Card. When I gives the 
reboot command to host and manually reboots the line Card also then its ok 
and no problem with eth0. But without resetting the Line Card at reboot time 
it has the same problem as freez the eth0.

So, I think the interrupt 11 for eth0  which is sharable with line card is 
not refreshing properly.

Can I refesh it by a script or is it internal problem?

Pl. reply

Best regards

Naveen
