I also have it on Kubuntu 9.04 amd64 with kernel 2.6.29. My most interesting facts are:
- I had this bounce key pb when installing from kubuntu 9.04 live CD! I had to restart with my mouse connected to the laptop to continue
- it only happens on my 7 ports D-link usb hub (DUB-H7), not on my hama 4 port hub
- does not happen on windows xp with same setup
- see outpuf of dmesg, lspci, lsusb, and uname in attached tgz
I really would like to see this bug getting a high priority:
- it's a widespread issue for several linux distributions and somehow Jaunty seems particularly affected
- it's a long standing issue (duplicate bug https://bugs.launchpad.net/bugs/91230 is 2 years old, reported on 6.10)
- the loss of keyboard and mouse is a serious showstopper for anyone trying linux especially when it happens during install
Please help!
I'm no kernel developer but I've been browsing a bit and here is the most interesting discussion I found:
http://<email address hidden>/msg18199.html
It basically says: --quote-- If I start with FC4's kernel configuration, and a
vanilla kernel, the mouse works correctly. If I then turn on kernel
preemption, and set HZ=1000, the problem comes up. Neither of those
settings, by themselves, seem to trigger the problem. -- unquote--
Duplicate bug https://bugs.launchpad.net/bugs/91230 may yield interesting information too. I any case, I'm pretty sure it's a tough longstanding kernel bug, so whoever gets to fix it will get kudos from many people and will help linux getting further (that bug already kept me away from migrating to Kubuntu a couple years ago).
