I'm pretty surprised that the upgrade from .25 to .25.1 alone caused the problem. Could you please retry with r206 and r207 and compare the results ? r207 introduces a patch to drop incomplete frames. Check the kernel log to make sure the right driver gets loaded (it should print the SVN revision number when loaded). If reverting to r206 helps, I'll ask you to try a patch to get more information about the issue.
