I got the following while trying to rsync a large number of files over
the network to a firewire HD (FAT32 FS) on a 6.0-BETA1 system.

IRQ 11 is my "super fun IRQ" with 90% of my hardware attached..
I am copying about 17000 45k files. The controller is the one built into my
Dell Inspiron 8600 ->

When I tried this earlier with 65000 much larger files I managed to get
rsync to use 125% of the CPU (no HT/SMP here)..
