Hi Alexander,
It's working fine now. (Tested with FreeBSD8 and Trendnet TEW-644UB
wireless adapter, and GENERIC kernel).
Thanks for your patch!

Hi Alex,
Here is the link to full problem report:
[2]http://www.freebsd.org/cgi/query-pr.cgi?pr=145761&cat=
I think this happens quite intermittently, usually once and shortly
after
it obtained a DHCP lease. Scrubbing the kernel core dump indicates a
'lock order
reversal' issue somewhere in the net80211/usb stack..
Best,

But i need more information about the problem you have or else i
cannot do anything.
When does the problem occur ? And how often ? Can you reproduce it
easily ?
Crash dump or debugger backtrace would be helpful to me.

Hi,
I have an issue running the rt2870 module with a Trendnet
TEW-644UB, can this be fixed using a native FreeBSD driver or the
one provided in Git
is the most current ? (it seems not to have such driver available
in 8.X.)
Alternatively, would there be a workaround to apply for using this
card
with FreeBSD 8 ?
Thanks!
