Hi all, So, I've been banging my head against the wall trying to work out what's going on here. I'm trying to access the channel utilization data that was added to cfg80211/nl80211's survey dump on an atheros card. It's been difficult to get a working kernel to do this, as the current master has the correct nl80211 patch, but not the ath5k one. I've pulled my tree to the latest version, and then cherry-picked the ath5k commit which adds the survey data to mac80211. Unfortunately, requesting a survey dump using the modified iw from the openwrt tree which should be able to extract the new information causes my kernel to panic. It appears to be dereferencing a non-existent pointer as the trace contains a line mentioning CopyToUser. I'm wondering if anyone has come across this problem and would know what's going wrong? I tried to get a kernel dump from the alix board we have, but it's now gone into a reboot cycle, and I can't fix it until Monday. Any help would be greatly appreciated.
