Herton,

Technically you are correct; however, I did extensive testing of
2.6.31 and _NEVER_ got the failure. The sequencing is a bug waiting to
happen, but something in the post 2.6.31 merge actually enabled the
bug to happen. I tried bisection to determine which change actully did
that, but was not successful.

My feeling is that stable can be left alone. Of course, if bug reports
of kernel panics on unload of rtl8187 start occurring, we will know
how to fix it.
