wireless dies: "kernel: NETDEV WATCHDOG: wifi0: transmit timed out"

Reported by: openwrt@… Owned by: developers
Priority: normal Milestone:
Component: kernel Version:
Keywords: Cc: openwrt@…

Description

I have openwrt on a fonera, with the network set up as follows:
internet <<wireless eap-ttls/pap>> (ath1)[fonera](eth0) <<wired switched lan>> [pc's]

When uploading, for example when using bittorrent, the wireless network will stop working after some time. It usually takes a few hours or so for this to happen, which translates to several GB of uploaded data traffic - unfortunately that makes this bug a very regular occurrence here. I do not know of any quicker way to trigger this bug.

The following message appears in the logs (repeatedly) when "shit happens":

user.info kernel: NETDEV WATCHDOG: wifi0: transmit timed out

After the first such message, the wireless stops working completely; even restarting the network doesn't bring it back to life, only a reboot does. Everything else, including the wired network, keeps working fine. No other errors are logged, nor any type of oops or crash.

openwrt r10457, kernel 2.6.23.16, madwifi 2.6.23.16+r3314-atheros-1

Now it also started happening without doing any significant upload data traffic, just a little downloading... only way to get a somewhat working access point is adding a check for this log message to cron to make it reboot :(

Still nothing in the log but that single line error message; note that iwconfig still shows the wifi associated with access points, just no dhcp or data traffic whatsoever happening.
