Yes, that would be my guess too ... although I don't see anything amiss
in the dmesg   I note you have two ethernet interfaces:

eth0: Sun GEM (PCI) 10/100/1000BaseT Ethernet 00:03:ba:08:61:7c
eth1394: eth1: IPv4 over IEEE 1394 (fw-host0)

I'm assuming eth0 is the problem?

Could you also send us the output of /proc/interrupts, /proc/iomem
and /proc/ioports just to see if we have a problem.  Also, if eth0 is on
its own interrupt line, does the interrupt count rise even while the
interface is non functional?

Thanks,

James
