On TI Panda 4460 board with Linux Linaro ubuntu image:

http://snapshots.linaro.org/ubuntu/pre-built/panda/596/panda-saucy_developer_20140126-596.img.gz

WiFi can't be enabled by set parameters in /etc/network/interface

auto wlan0
iface wlan0 inet dhcp
wpa-ssid SSID
wpa-psk PASSWORD

This feature worked well on build 592 at least.

http://snapshots.linaro.org/ubuntu/pre-built/panda/592/panda-saucy_developer_20140120-592.img.gz

Also, this command runs failed:

root@linaro-developer:~# service networking restart
stop: Unknown instance:
start: Job failed to start
root@linaro-developer:~#

And it worked well on build 592 too.

2) 'service networking restart' worked too...

3) I has been hit by the following once:
-----8<-----

-----8<-----
But it didn't cause any bad consequences.

So this is not "build 592 is good, and build 596 is bad" unfortunately. Ruther looks like instability.
I'll let the board to run build 596 for a while to see if anything bad happens.

Also builds 592 and 596 are very similar WRT the kernel. The former uses ll-20140120.0, the latter - ll-20140124.0, and *the only* differences between the kernel source trees are just CONFIG_NETFILTER_XT_MATCH_CONNTRACK=m added to distribution.conf, and few changes to beaglebone.conf. The kernel configs from these two builds are slightly different, but it shouldn't matter in this case:

BRIDGE_EBT_T_FILTER n -> m
NETFILTER_NETLINK_LOG n -> m
NETFILTER_XT_MATCH_CONNMARK n -> m

On TI Panda 4460 with Linux Linaro ubuntu image:

http://snapshots.linaro.org/ubuntu/pre-built/panda/616/panda-saucy_developer_20140323-616.img.gz

WiFi now works well after manually set the SSID and password in file "/etc/network/interfaces". And it also works well with Ethernet at the same time.

Test log has been attached.

But there may still be a minor issue as described in comment #5 of Bug 1274057

WiFi works well.

The issue described in comment #5 of Bug 1274057 is not observed this time.
