I am getting stack traces (see below) on my broadcom 4318 card, they are
always started off at b43/xmit.c:76 (function
b43_plcp_get_bitrate_idx_ofdm) and mac80211/rx.c:2183 (function
__ieee80211_rx) both are hitting the WARN_ON macro references. Does
anyone know why this may be happening? It doesn't seem to cause any trouble.
The code blocks are:
__ieee802111_rx:
if (!sband ||
status->rate_idx < 0 ||
status->rate_idx >= sband->n_bitrates) {
WARN_ON(1);
return;
}
and
xmit.c:
case 0xB:
return base + 0;
case 0xF:
return base + 1;
case 0xA:
return base + 2;
case 0xE:
return base + 3;
case 0x9:
return base + 4;
case 0xD:
return base + 5;
case 0x8:
return base + 6;
case 0xC:
return base + 7;
}
B43_WARN_ON(1);
return -1;
I am using Linux 2.6.26 on an ARM processor. The uname -m is armv5tel,
uname -r is 2.6.26.
