SubjectRe: [linux-usb-devel] [2.6.0-test2-bk5] OHCI USB printing causing system lockup...
It does seem that it's the usblp driver, and I think the way forward is to
collect more information with compiling the driver with debugging to see more
of what's happening here. I'll do this tonight and report findings.

The module author string is "Michael Gee, Pavel Machek, Vojtech Pavlik,
Randy Dunlap, Pete Zaitcev, David Paschal" - who should I CC my results to?

Thanks!
