sysrq only appears to oops in usb modules :( I've built all the
required items (usbcore, ohci, sound, & audio) into the kernel and can
now get a sysrq-t trace. There are four processes running for xmms at
this point. Generally I can kill all but one with a kill -9 (should be
the first one in this list.) That one will not respond to a kill -9,
and it seems to hold the usage count on the usb audio module.:

Would line numbers for any of these be helpful? I've got the vmlinux
