If it were me I'd probably start adding diagnostic printouts to the
twa driver to try and figure out exactly where and why it's hanging.
But I've done a lot of kernel hacking over the years and I'm
comfortable doing that kind of thing.
There seems to be a TWA_DEBUG setting you could compile the kernel
with, but it doesn't look like it does much.
Compiling a kernel with DIAGNOSTIC and/or DEBUG enabled might help but
probably won't. I don't have any other bright ideas, but Manuel or
someone else might.
