reporting bugs to 12.04

[Michael]

What is the procedure to report bugs for version 12.04?  I'm seeing the 
bug that affects the network connection.  In the log viewer I'm seeing 
the following error.


Dec 22 10:46:39 mike-Vostro-1000 kernel: [ 3906.169752] wlan0: 
authenticate with 50:46:5d:6d:30:20 (try 1)
Dec 22 10:46:39 mike-Vostro-1000 kernel: [ 3906.368101] wlan0: 
authenticate with 50:46:5d:6d:30:20 (try 2)
Dec 22 10:46:39 mike-Vostro-1000 kernel: [ 3906.568094] wlan0: 
authenticate with 50:46:5d:6d:30:20 (try 3)
Dec 22 10:46:40 mike-Vostro-1000 kernel: [ 3906.768087] wlan0: 
authentication with 50:46:5d:6d:30:20 timed out

I want to report it but I'm not sure if its still valid to report or add 
information to a bug if its an older kernel.
