There are 2 versions, one for amd64 (64bits) and other for i386 (32bits). Please give it a try to see if it solves the problem and, if possible, report back with a dmesg. Remember to install, at least, the linux-image-* and the linux-image-extra-* packages. Thanks.
We believe we found the root cause and I've uploaded a test kernel that will fix the issue. You can download the test kernel here:
