    • Environment:

      IBM BladeCenter-E chassis, model 86773RU

      Description

      The keyboard and mouse subsystems are nearly unusable in recent versions of XenServer on IBM BladeCenter-E chassis.

      Upon switching to a new console, both mouse and keyboard are usable before becoming completely unresponsive after only a few seconds of inactivity.

      The problem is caused by recent versions of the kernel defaulting to autosuspend the USB subsystem.

      A workaround can be applied by booting up with the following kernel parameter:

      usbcore.autosuspend=-1
