 Hi,
 
 Thank you for testing. It tells med that the IRQ routing is broken 
 somewhere.
 
 Could you binary search the kernels between r249786 and r251254, to 
 figure out the exact commit that broke your XHCI driver, reverting my 
 patch? You should not need to build the kernel more than 10 times before 
 you figure out which has the commit which causes the failure.
 
 make buildkernel -j8 -DNO_CLEAN
 
 If you checked out the sources using GIT, this should be very quickly done.
