Using dapper and kernel 2.6.15-21.32 I get the same error:

The last two lines are repeated more than 100 times.

According to http://forums.debian.net/viewtopic.php?t=4338& this problem is resolved in linux 2.6.16-4. (I guess he means 2.6.16.4).

Does that make it impossible to fix before dapper is released?
