Resend(oops, never setup plain text vs html on this machine)

I've been getting spammed with: 

iwlagn 0000:03:00.0: iwlagn_tx_agg_start on ra = 00:0c:42:64:bb:1d
tid = 0

Every 35s for the 16 hours my machine has been up:

anvil $ uname -a
Linux anvil 2.6.39-gentoo #1 SMP PREEMPT Fri May 20 01:53:54 EDT
2011 x86_64 Intel(R) Core(TM) i7 CPU Q 820 @ 1.73GHz GenuineIntel
GNU/Linux

anvil $ dmesg | grep iwlagn_tx_agg_start | wc -l
1621

anvil $ uptime
 16:44:40 up 14:49,  3 users,  load average: 1.11, 0.82, 0.48

Is there a good reason to print this message?  Is it indicative of a
problem?  Everything works fine.

Here's a little dmesg info from my system:
