 I've also tested with an MP machine and I doubt that may have any
 impact on this problem.
 Could you please try whether the following patches make any
 difference for you?
 http://people.freebsd.org/~kan/usb_rspro.diff
 http://people.freebsd.org/~marius/usb_busdma.c_sparc64_no_hack.diff
 Please also test how the machine behaves if you leave ehci(4) out
 of the kernel so uhci(4) is used instead.
