Hi,
I'm having trouble running wifi in combination with a rt enabled kernel
3.0.9-rt26 on an imx51 arm platform. The distro is openwrt-trunk.
The device has 2 usb wifi interfaces (AR9271 chipset; driver: based on
compat-wireless-testing 2011-12-01). I am running an iperf load on both
interfaces, one interface is in AP mode, the other in STA mode.
When I configure the kernel without RT preemption, the device runs
stable for >10 hours.
With RT preemption enabled, after a couple of minutes some interface
will stop transmitting data. Sometimes ifconfig wlan[0,1] down will
hang, sometimes ifconfig wlan[0,1] down will work, but then ping will
return the following:
# ping 192.168.2.170
PING 192.168.2.170 (192.168.2.170): 56 data bytes
ping: sendto: Operation not permitted
Right after loading the wireless drivers I get the following kernel
warning:

[ 91.890617]
[ 91.890620] which lock already depends on the new lock.
For a while the network interfaces will transmit data normally though.
The configuration I use is far from optimal, both wireless drivers, as well as
the kernel contain the openwrt patches. If requested, I'll provide traces from
the vanilla sources.
I could reproduce the same behavior with kernel 3.0.14-rt32.
Could anyone help me to figure out a solution to this problem?
Kind regards,
Christian Kapeller

Just my 5 cents: I am working on the imx 35 platform and i am also having
problems with the network setup. I have sent a bugsplat to this list which
occurs in the network setup with 3.2-rt. I suspect that these two errors are
related. Steven Rosted wanted to look after it, but it seems he hasn't until
now.
Best regards
Tim

This doesn't look related to you other troubles. But I'm curious to why
this happened. Seems to be the timer lockdep code is triggering here,
which is made to protect against bad del_timer_sync() actions. But
that's not the case here. I'm not sure what that "port_lock_key" is.
Could you post the rest of that locked splat. There should be a lot more
useful information.

Ah that explains it ;-) Yeah that would be helpful, as I could then look
at the code those back traces represent.
Thanks!

Yeah, I've been hunting down other nasty bugs in the mean time. I could
start looking at this. I suspect it may be due to another try_lock()
thingy.

Hi,
thank you for investigating this. I could reproduce the issue with with
v3.0.9-rt26 from rt stable git patches, and the
compat-wireless-2011-12-01 sources. The arch specific stuff came to me
as one big 1 MiB patch, which I hesitate to attach here. Here is a link:

That's openwrt related patches. They regularly take compat-wireless snapshots,
and apply a number of patches against that. Openwrt comes as buildroot

Please do not remove Cc's! I may only read this mailing list a couple of
times a week. If you want me to see your reply, Cc me. When I'm on a
thread, I will usually ignore replies in the mailing list, because I
expected to have read it in my inbox. Thus I may not even see your
replies.
I know some other mailing lists ask to just reply to the list and not to
Cc. I never listen to them :-) That's just a list maintainers arrogance
thinking that everyone reads the list every day. I don't and seldom do.
I have enough trouble keeping up with my inbox to read mailing lists.

I applied it, and I still don't see the line number to below in rx.c.

Does the above patch have the changes to the rx.c file?

My file (with above patch applied) only has 2963 lines. I don't know
where that 2981 comes from.
What's at that line there (can you send the rx.c file).

This one has:
send_mac80211:
spin_lock_bh(&priv->tx.tx_lock);
if (WARN_ON(--priv->tx.queued_cnt < 0))
priv->tx.queued_cnt = 0;
spin_unlock_bh(&priv->tx.tx_lock);
looks like the tx.queued_cnt got corrupted.

This is definitely a bug!
In drivers/tty/serial/imx.c: imx_set_termios()
spin_lock_irqsave(&sport->port.lock, flags);
[...]
del_timer_sync(&sport->timer);
If the timer is on another CPU and tries to grab the sport->port.lock,
but blocks while this code is holding the spinlock. We deadlock.
The del_timer_sync() will spin until the timer in question is finished,
but the timer in question could be spinning on the spinlock that is held
here.
But this is a separate issue. I don't think this is the cause of your
original problem.
