Carla, Where did you dd the Ubuntu image, SD card or USB disk? I normally dd the image to a SD card, because the Panda board needs to boot up from SD card. It is not supposed to boot up from USB disk directly. Or you just installed the whole system on a USB disk and still boots from SD card?

From Eric's reply, I found this issue is a little bit complex to backport some patches from 3.6-rc1, because from 3.5 to 3.6-rc1 some fundamental stuffs were changed. -- As I recall the routing cache was removed between 3.5 and 3.6-rc1 so there are some significant changes to the fundamentals.

As Eric W. Biederman said in the bugzilla, 3.6-rc1 mainline version works. I've testing our Ubuntu mainline build like 3.6-rc1 and 3.6-rc5, which all work fine. But for 3.5.3 mainline build, this test failed. Our latest Quantal kernel is based on 3.5.3 kernel. So obviously this issue was fixed

I can reproduce this as Stephane's mentioned, but I only got message like unregister_netdevice: waiting for lo to become free. Usage count = 2. There is no other oops messages like mutex_lock() and I think the oops is because lxc-start was blocked for too long. So probably the subject of this

We got a very critical issue on an Intel machine with 4 cores and 8 threads CPUs. Since we got 4G RAM, we are using 32bits -pae kernel. ureadahead will try to get 128M trace buffer percpu, so it will allocate 128M * 8 = 1G RAM. Normally it will be killed by OOM, but system cann't boot at all
