wpi0: fatal firmware error

I have a new Dell Latitude D530 laptop with builtin
wireless.  During boot up, I see

wpi0: <Intel(R) PRO/Wireless 3945ABG> mem 0xfe8ff000-0xfe8fffff irq 17 at device 0.0 on pci12

ifconfig wpi0 ssid "HomeNetwork" mode 11g channel 11 wepmode on

I see an endless stream of

Is this a known problem?
