 =46rom the looks of it (with your patch at
 http://people.freebsd.org/~marius/usb_busdma.diff), the machine starts
 booting, then tries to mount the filesystems residing on the USB disks,
 apparently does some I/O (while still processing interrupts), and after
 less than a minute locks up solid without any indication on the serial
 console as to what went wrong...
 
 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!
 
 Manuel
