There are some early issues of the SiI3112 chips that has problems that
can cause datacorruption etc etc..
You can try the following patch (which btw re@ has for approval),
otherwise I'd try another controller as there seem to be no end of the
troubles with the Sii 3112 chips (brings back to mind the horror times
from when they where called CMD and did the CMD640 disaster)...
