Subject: Kernel crash when "requesting rt73.bin"

Hi

   I am running linux on mini2440 (ARM based).

I am able to load most of the drivers and run fine.

When I load rt73usb.ko , I get a crash.

I have copied rt73.bin from my ubuntu 9.1 (x86) to /lib/firmware. Hope
that is OK
as it is a data file. If not, how do I compile it. I have tried commenting out
#CONFIG_STANDALONE
#CONFIG_PREVENT_FIRMWARE_BUILD
#CONFIG_FIRMWARE_IN_KERNEL

This creates .bin for many drivers but none for rt73.

The crash messages is below. I can provide any other info, if required

Thanks
linketu
