I don't think so.  It appears to be a driver or firmware issue.  As a 
workaround, try adding

	options ipw2200 hwcrypto=0

to /etc/modprobe.conf.  It seems to drastically reduce the number of these 
errors.

If you are bold and want to try the latest drivers (which may fix the 
porblem), see http://www.ces.clemson.edu/linux/fc2-ipw2200.shtml.
