I've started another build with your "VIA quirk fix" but without the patch in the last paragraph (the machine locking up is a lot worse than just USB not working after some heavy I/O, so I left it out for now), but since I started the build without being properly awake this morning, I typed "make buildworld" where I wanted to type "make buildkernel", so it's going to take some time. Also, I'll be leaving CERN over easter, so I won't be running tests on that machine from tomorrow morning until Monday evening (I can compile kernels, though). Anyhow, I'll let you know what comes out. Cheers, thanks a lot for your effort, and, of course, a Happy Easter!
