I have seen this, too. I think it is a bug in the rate adaptation code. I
don't see what it would have to do with building a release, unless the
kernel misses interrupts under those conditions....

Ok, the firmware should "never" return a bad index, but obviously I
should not trust that. Bug noted.

Hmm. This could be an endianness issue. What architecture is this?  I am
betting that it is big-endian.  0x6e (110) is Prism's representation for
11Mbps. The data rate and the index both go into the same 16-bit word,
but they are u_int8_t's in the wi_frame struct.
