[Asterisk-Dev] Indirect Registers failed verification

[Dinesh Nair]

hi * folk,

inconsistently, the zaptel drivers on freebsd 4.10 fail with the following 
messages repeated ad nauseaum. since this portion of the freebsd zaptel 
drivers are exactly the same as the linux zaptel drivers, i'm wondering if 
anyone has seen this error (see error log below) before and what it would 
possibly indicate. this happens inconsistently, and i can't seem to 
reproduce it at will, though it seems more common if i take a phone 
onhook/offhook frequently and is usually triggered by a power alarm on a 
module. any pointers are much appreciated.

i notice that this is stemmed from an interrupt and is handled here as follows:

if (ints & 0x0f) {
	sc->intcount++;
	x = sc->intcount % 4;
	if ((x < sc->cards) && (sc->cardflag & (1 << x))) {
		if (sc->modtype[x] == MOD_TYPE_FXS) {
			wcfxs_proslic_check_hook(sc, x);
			if (!(sc->intcount & 0xfc))
				wcfxs_proslic_recheck_sanity(sc, x);
		} else if (sc->modtype[x] == MOD_TYPE_FXO) {
			wcfxs_voicedaa_check_hook(sc, x);
		}
	}
	if (!(sc->intcount % 10000)) {
		/* Accept an alarm once per 10 seconds */
		for (x=0;x<4;x++)
			if (sc->modtype[x] == MOD_TYPE_FXS) {
				if (sc->mod.fxs.palarms[x])
					sc->mod.fxs.palarms[x]--;
			}
	}
	wcfxs_receiveprep(sc, ints);
	wcfxs_transmitprep(sc, ints);
}

also, why is the sanity check only called when (intcount & 0xfc) == 0 ?
