Bug Description
My keyboard and mouse often stop working. It usual happens when I am typing something. This happens _very_ often (happens to me ca once per hour).
Steps:
1. type as usual
What happens
Keyboard becomes completely unresponsive (CAPS, NUMLOCK not working). Last key/key combination typed gets repeated (appears many times on xterm or editor, etc...)
Expected:
Keyboard keeps functionning properly.
Known work-around(s):
The machine is still running properly and I usualy have 2 solutions to solve the issue:
* perform a suspend/resume cycle (note: I use the following default kernel options in grub # defoptions=quiet splash acpi_sleep=s3_bios i8042.nomux i8042.reset ). This of course tends to break my network
* ssh into the box and force a keyboard driver reload using:
$ cat local/bin/
echo -n "i8042" > /sys/bus/
echo -n "i8042" > /sys/bus/
(this script comes from #214985)
This solves my problem. There's never been anything interesting in dmesg (no i8042 message related at all)
Misc:
* Hardware: Lenovo 3000 N100.
* Distrib: Hardy as of 13/Apr/2008

Today, resuming from suspend (albeit a longer one than usually, not sure if that affects), didn't reproduce this problem. First time in a long time. On the other side, this time wireless didn't come up and I had to do this:
rmmod iwl3945
rmmod iwlwifi_mac80211
modprobe iwl3945
to fix it. Note: wireless was I think disconnected when I put the machine to sleep.
I will try to see if both problems always exclude each other. I will also try to see if I can reproduce the wireless doesn't come up problem. I used to experience it, but it appears that I forgot to open an issue in launchpad.
