Description of problem:
USB keyboards on Dell GX280 machines will randomly and frequently (i.e. once every 4-5 hours of continuous use) stop working. Disconnecting and connecting the keyboard on a difference USB port generally fixes the problem.
Note that the USB keyboard relies on USB modules, as there is no PS/2 emulation on the GX280 (or PS/2 emulation doesn't kick in automaticaly). After verification, no corresponding setting were found in the BIOS to emulate a PS/2 keyboard.
The problem occurs in all runlevels, and seems to indicate a limitation in the ehci-hcd or uhci-hcd drivers.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot the system normaly using a USB keyboard on a Dell GX280.
2. After a while, the keyboard will stop responding.
This is different from bug 165942 filled earlier.
