Comment 4 for bug 1002951

After rebooting I carried on using the USB keyboard, and after a while it suddenly stopped working. The PS/2 keyboard works fine. So it seems like the problem is 'first keyboard' stops taking input - nothing specific to USB.

The machine was up for 1h 45m waiting at login prompt, then I used it for about 40 mins before the keyboard stopped working.

staus info:

xev just provides a MappingNotify event - no keypresses:
MappingNotify event, serial 34, synthetic NO, window 0x0,
    request MappingKeyboard, first_keycode 8, count 248

$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Microsoft Microsoft 5-Button Mouse with IntelliEye(TM) id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Power Button id=7 [slave keyboard (3)]
    ↳ CHICONY USB NetVista Full Width Keyboard id=8 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]

$ dmesg | grep CHIC
[ 1.983626] input: CHICONY USB NetVista Full Width Keyboard as /devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1:1.0/input/input3

$sudo evtest /dev/input/by-path/pci-0000\:00\:1a.0-usb-0\:1\:1.0-event-kbd

shows key events on dead USB keyboard.

So situation is exactly as before but the other keyboard has got 'jammed' instead.

(I used the 'extra' keyboard for 2 full days with no further issues last time. We'll see what happens this time).

Any clues for other things to check?
