[1.] One line summary of the problem: "lsusb -v" as root freezes the kernel on Acer ES1-111M [2.] Full description of the problem/report: As root, "lsusb -v" against USB devices "003:001" or "003:002" of my Acer ES1-111M netbook freezes the kernel. No log entry, no oops, no magic sysreq key. Reproducible: always. There are only those two devices on bus 003. There is no problem with the other USB buses or devices of the machine. I have no external USB devices attached. When I had, there was no problem with them.

I reported this problem against Ubuntu and was asked to raise it upstream. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1485057 I used the pre-built mainline kernels for verification of the problem, hope that is OK. http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D cheers and thanks, Roland -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
