It may be intermittent, a bug, or even a false alarm. Please consider this void unless someone else can confirm.
Still I often run into this. Warm and cold reboots do not cure it. I have no clue where to start investigating. Suggestions welcome.
Upgrade to kernel-2.6.30.8-64.fc11.i586. The problem still persists. Back to kernel-2.6.29.6-217.2.16.fc11.i586 again. I have no clue where to start investigating. Suggestions welcome.
Can you try adding 'i8042.noloop=1' to the boot options? Also try 'i8042.nomux=1'.
Thanks for the suggestions! With 'i8042.noloop=1' the touchpad is correctly detected. 'i8042.nomux=1' makes no apparent difference (i.e., no touchpad).
This patch might fix the problem then: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=1c7827ae70e7c8456e08f7bb9ef2238d27814cbe
