 I could reproduce the problem. Yes, it's my fault.

 I sent a new pullup request:

	http://releng.netbsd.org/cgi-bin/req-8.cgi?show=361

It's little hard to fix that problem with small patch. I'm going to
send a jumbo patch for ixg(4) to fix a lot of bugs and it'll fix this
problemcleanly.

 Sorry and thank you all.
