we have a test version of DriverLoader with the do_softirq and "if 
(!current->fs->root)" problems that should be be solved. It can be 
downloaded at:


Please report if these problems were solved or not on your setup.

Note that the USB related symbols exported with EXPORT_SYMBOL_GPL is a 
known problem and we are currently working on this. There is no fix for 
that in the test version above.
