Well yes, I add one patch for reducing the usb device resetting time, but this was definitely not the problem, no usb device was attached. from the cache, so racing is not a issue there. Possible random memory corruption? Could be could be. I would say since it is such a strange thing and nobody has an idea we leave it for now, random memory corruption sounds nice. If it occurs I can come back.
