Hi,

I think the trouble starts with "unregistered net_device". It looks
like some structures in memory are corrupted.
I don't think that is the problem. The output from booting the kernel
says "unregistered net_device" as well:

Oh well. Then you need to add some tracing to
lbs_set_11d_domain_info(). I do it the old way. I put this macro to
the beginning of the file:
#define MARK printk("%s:%d %s()\n", __FILE__, __LINE__, __func__);
And then I add "MARK" to every second line, as long as it's permitted
syntactically. I may skip adding MARK where failures are unlikely, such
as initialization of local variables. Once you find the line where
printing stops, print all variables used on that line.
I would also print the arguments as pointers in the beginning. Maybe
they are corrupt.
