No, sorry.
The bug is still here.
The generic kernel fails after some chars (e.g. 5) and repeats the  
last char
for 4 rows. The next char is repeated for 6 rows and now the keyboard  
is locked up.
After some time the keyboard is usable again.

The wscons kernel stops printing chars to the console and also need  
much longer to recover.
It does not print those keyboard translation error messages to the  
console.

vmstat while repeating chars (using generic):

-bash-3.2$ vmstat -i
interrupt                                     total     rate

The timing seems to be really messed up, because with the log output  
the bug disappeared.
