Hello,
Sorry for the incomplete information.
My OS is uCLinux (linux kernel 2.4.10) . Whenever I start a high transfer
through the wireless interface the system crashes, sometimes it hangs
without any messages in the console. Here is the oops message.

Kernel unaligned instruction access in unaligned.c:do_ade, line 428:
