                                               ^^^^^^^
I think it is a module from the old usb stack.

I also see automatic loading of the old stack modules,
for example (entries 17, 18):

19    1 0xffffffff80c2e000 216      green_saver.ko (/boot/kernel/green_saver.ko)

Simple kldunload-ing of ums.ko unloads usb.ko also.

I am having quite reliable panics with the new stack when I insert
usb stick (actually during the first access to it).
Trying to collect more information I haven't managed to produce
memory dump. Is it working on amd64 SMP CURRENT? I remember there were
some complains about it.
I will report details of the panic when I get them.

Alexey.
