"lsusb -v" as root freezes the kernel on Acer ES1-111 |
"lsusb -v" as root freezes the kernel on Acer ES1-111; also freeze on shutdown |

description |
reproducible: always
Steps to reproduce:
- open a terminal
- sudo bash
- lsusb -v
In a virtual terminal, the command prints the name of the first device it finds, then the system freezes completely. In a terminal of the desktop, I don't even get the name of the device, the system freezes immediately. Either way, I have to power off the machine. There is no kernel oops. Nothing is written to the log. The magic sysreq key yields no response, although I have verified that it works before triggering the freeze.
I've narrowed down the problem by calling "lsusb -v -s <device>". The system freezes on both devices of bus 3 (003:001 and 003:002). For all other devices, it prints the expected output and continues to work. When calling lsusb as a regular user, I get "Couldn't open device, some information will be missing", then the regular output, and the system keeps running. Therefore I assume that the problem is somewhere in the kernel, when the devices are accessed.
This is a regression. It used to work in 14.10, and fails to work since 15.04.
It also used to work in 14.04.2, and fails in 14.04.3.
It fails with mainline builds 4.2.0-rc6-unstable, 4.2.0-rc2-unstable, 4.1.0-rc2-vivid. (yeah, I've been trying for a while :-)
Incidentally, the shutdown sequence also freezes early on with the kernels that exhibit the problem; but I cannot be sure that the cause is the same. I decided to first chase the USB freeze, because it was easier to gather information about that.
