Hi,
I 'm running "OpenBSD 4.4-current (RALDBG) #0: Fri Oct 10 16:56:50 CEST
2008", which is GENERIC with RAL_DEBUG, but I've seen this problem with
previous kernels and without RAL_DEBUG, too.
# dmesg | grep ral
ral0 at pci0 dev 14 function 0 "Ralink RT2860" rev 0x00: irq 10EEPROM
rev=1, FAE=1
ral0: MAC/BBP RT2860 (rev 0x0101), RF RT2820 (2T3R)
This is a pci Edimax EW-7728IN, which I believe is the same card that was
donated to damien@ (?) and that led to 28xx support.
After an unfixed amount of time, from a few minutes up to a few days, the
interface simply stops respoding to probe requests:
# tcpdump -nvvveeees 1000 -i ral0 -y IEEE802_11_RADIO not subtype beacon
14:17:40.761912 CLI1-MAC > ff:ff:ff:ff:ff:ff, bssid ff:ff:ff:ff:ff:ff (seq
16): 802.11: probe request, <radiotap v0, 1Mbit/s, chan 6, 11g, sig -19dBm,
antenna 2, signal 17dB>

14:21:03.860025 CLI2-MAC > ff:ff:ff:ff:ff:ff, bssid ff:ff:ff:ff:ff:ff (seq

14:21:04.306901 CLI2-MAC > ff:ff:ff:ff:ff:ff, bssid ff:ff:ff:ff:ff:ff (seq
1520): 802.11: probe request, <radiotap v0, 1Mbit/s, chan 6, 11g, sig
-23dBm, antenna 1, signal 21dB>
Whereas normally you'd see the probe req, probe resp, auth req, auth resp,
assoc req, assoc resp, wpa dance.
# tcpdump -nvvveeees 1000 -i ral0 -y IEEE802_11_RADIO | grep beacon | grep
AP-MAC
Shows that it stops sending beacon frames. It's still picking up the
beacons from the 5 other wlans it can see, so rx seems to work fine.
# ifconfig ral0 down && ifconfig ral0 up
Fixes everything, until it happens again after a seemingly random interval.
The kernel doesn't log anything unusual even with RAL_DEBUG.
I suppose I should sendbug, but I think lots of people have these cards so
I'd like to know if anyone else is seeing this. Any ideas?
Thanks and please cc,
bbee
