 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.
