Ladies and gentlemen,
I acquired a new keyboard and now this new kbd presents itself as a
multiple input device. In following evtest output, kbd devices are 2
and 7 with difference that 7 offers some media keys as well (listing
#2 lists additional keys):
listing #1, available devices:
/dev/input/event0: Power Button
/dev/input/event1: Power Button
/dev/input/event2: ROCCAT ROCCAT Vulcan 120 AIMO
/dev/input/event3: ROCCAT ROCCAT Vulcan 120 AIMO Mouse
/dev/input/event4: ROCCAT ROCCAT Vulcan 120 AIMO Consumer Control
/dev/input/event5: ROCCAT ROCCAT Vulcan 120 AIMO System Control
/dev/input/event6: ROCCAT ROCCAT Vulcan 120 AIMO
/dev/input/event7: ROCCAT ROCCAT Vulcan 120 AIMO
/dev/input/event8: Kensington Kensington Slimblade Trackball
/dev/input/event9: Logitech K800
/dev/input/event10: Logitech Performance MX
/dev/input/event11: HDA ATI HDMI HDMI/DP,pcm=3
/dev/input/event12: HDA ATI HDMI HDMI/DP,pcm=7
/dev/input/event13: HDA ATI HDMI HDMI/DP,pcm=8
/dev/input/event14: HDA ATI HDMI HDMI/DP,pcm=9
/dev/input/event15: HDA ATI HDMI HDMI/DP,pcm=10
/dev/input/event16: HDA ATI HDMI HDMI/DP,pcm=11
/dev/input/event17: HDA ATI SB Rear Mic
/dev/input/event18: HDA ATI SB Line
/dev/input/event19: HDA ATI SB Line Out Front
/dev/input/event20: HDA ATI SB Line Out Surround
/dev/input/event21: HDA ATI SB Line Out CLFE
/dev/input/event22: HDA ATI SB Line Out Side
listing #2, additional event codes on event 7:
Event code 140 (KEY_CALC)
Event code 142 (KEY_SLEEP)
Event code 150 (KEY_WWW)
Event code 152 (KEY_SCREENLOCK)
Event code 158 (KEY_BACK)
Event code 159 (KEY_FORWARD)
Event code 161 (KEY_EJECTCD)
Event code 163 (KEY_NEXTSONG)
Event code 164 (KEY_PLAYPAUSE)
Event code 165 (KEY_PREVIOUSSONG)
Event code 166 (KEY_STOPCD)
Event code 173 (KEY_REFRESH)
Event code 176 (KEY_EDIT)
Event code 177 (KEY_SCROLLUP)
Event code 178 (KEY_SCROLLDOWN)
Event code 179 (KEY_KPLEFTPAREN)
Event code 180 (KEY_KPRIGHTPAREN)
Now the problem is that when pressing a key like caps lock or num lock
that causes actual data to be sent from the system to the input device
driver like e.g. EV_LED, random key code starts repeat. Usually this
key scan code is 185 which seems to respond F_15 which is non
physically existent. Sometimes it is KEY_A and sometimes it comes
(repeated a's) through to cli making terminal useless. Repeat interval
seems match with about 330msec. I have tested this without X on multi
user non graphical runlevel and wmi modules black listed without any
effect. Problem persists. I have also tested with actual physical
secondary keyboard and have been able to trigger this anomaly also
from there. Have to mention that when problem triggers, USB bus is
calm, any such URBs that does not belong there or are erroneously
extra URBs, exist.
listing #3, spurious repeat triggered:

How should I continue? Should I place an bug report but to upstream or
Fedora's own bugzilla?
Sincerely,
Juha
