You might try using an older kernel with your > decaying trackball to see. Umm.. I've *been* using it with older kernels for *months*. Not a *single* hit in my logs, which go back till June 10. Except for today, when I started running -0716, and now I've gotten hit by the same messages, and then the same hang 4 times today. So either the codepath in -0716 is different from -0702 and -0604 and -0517 and every other -mm before, or the trackball spontaneously developed a *different* behavior overnight at the same time I upgraded the kernel. See the logs below... > This is a bug. For more discussion see this thread: > > http://marc.info/?t=124807676700001&r=1&w=2 > > You should try the patch given there. OK, will do that, see if it improves things... The logs back to June 10 (and I was on vacation Jun 20-26): % egrep -h 'USB disc|reset device' mess* | grep -e '-8.3' Jun 10 12:05:22 turing-police kernel: [93125.340042] usb 1-8.3: USB disconnect,
