Dual G5.  My kernel panics are of two types,

1) [lusol@Dragonfly:/Library/Logs] grep vnreclaim panic.log
panic(cpu 0): vnreclaim: v_usecount
panic(cpu 0): vnreclaim: v_usecount
panic(cpu 0): vnreclaim: v_usecount
panic(cpu 1): vnreclaim: v_usecount
panic(cpu 1): vnreclaim: v_usecount
panic(cpu 1): vnreclaim: v_usecount
panic(cpu 1): vnreclaim: v_usecount
panic(cpu 0): vnreclaim: v_usecount
panic(cpu 1): vnreclaim: v_usecount
panic(cpu 1): vnreclaim: v_usecount

2) [lusol@Dragonfly:/Library/Logs] grep afs panic.log
panic(cpu 0): Increase -stat parameter of afsd(VLRU cycle?)
          org.openafs.filesystems.afs(1.2.10)@0x29f57000
panic(cpu 0): Increase -stat parameter of afsd(VLRU cycle?)
          org.openafs.filesystems.afs(1.2.10)@0x28ecb000

I have no data here - dual G5 and 10.3.x is current setup, previous 
setup was a Cube and 10.2.x.
