Title: Call trace when testing fstat stressor on ppc64el with virtual keyboard and mouse present Status in Linux: Unknown Status in linux package in Ubuntu: In Progress Bug description: Ubuntu 16.04.1 Kernel = 4.4.0-53-generic-74-Ubuntu ppc64le When running the stress-ng "fstat" stressor, it is trying to access the USB bus and giving a call trace and locking up any further USB activity (lsusb hangs). This only seems to occur so far on openpower(Firestone and Garrison) where there is a virtual USB keyboard and mouse built into the BMC. From lsusb(before crashing): Bus 001 Device 004: ID 046b:ff10 American Megatrends, Inc. Virtual Keyboard and Mouse Another openpower server(Briggs) has no virtual usb devices and does not experience the failure. Please see attached kern.log and dmesg output for further details.
