Hello David!
I have exactly the same problem of Meelis on my Sun Ultra Enterprise 3000.
Here's the output of my /proc/interrupts :
berta-test:~# cat /proc/interrupts
CPU10 CPU14
0: 8346 7272 <NULL> timer
2: 7 0 sun4u zs
4: 0 0 sun4u SYSIO_UE
5: 0 0 sun4u SYSIO_CE
6: 0 0 sun4u SYSIO_SBERR
13: 0 0 sun4u SYSIO_UE
14: 0 0 sun4u SYSIO_CE
15: 0 0 sun4u SYSIO_SBERR
19: 1676 0 sun4u eth0
20: 1604 11293 sun4u ESP
22: 0 0 sun4u SYSIO_UE
23: 0 0 sun4u SYSIO_CE
24: 0 0 sun4u SYSIO_SBERR
31: 0 0 sun4u SYSIO_UE
32: 0 0 sun4u SYSIO_CE
33: 0 0 sun4u SYSIO_SBERR
38: 15 0 sun4u ESP
39: 0 7 sun4u ESP

Hope it can help to solve the problem!
