The problem is that when you enable TurboA mode - ieee80211_chan2mode()
returns index 5, and tries to get flags using ath_chan2flags() from
array modeflags.
This array contais only 5 elements (some time ago the array was
reduced). And when element modeflags[5] is requested the result is
unpredictable.

Simple fix would be to add one element to the array modeflags:

In file if_ath.c

static u_int
ath_chan2flags(struct ieee80211com *ic, struct ieee80211_channel *chan)
{
	static const u_int modeflags[] = {
		0,			/* IEEE80211_MODE_AUTO */
		CHANNEL_A,		/* IEEE80211_MODE_11A */
		CHANNEL_B,		/* IEEE80211_MODE_11B */
		CHANNEL_PUREG,		/* IEEE80211_MODE_11G */
		CHANNEL_PUREG,		/* simple pad to make CHANNEL_T the 5'th element */
		CHANNEL_T		/* IEEE80211_MODE_TURBO */
	};
	return modeflags[ieee80211_chan2mode(ic, chan)];
}
