Re: Kernel crash when using multiple interfaces

[Simon Vincent <simon.vincent@xsilon.com>]

Hi Alex,

I can confirm your patch still results in the bad paging request.
Maybe you are not seeing it as you have a slightly different setup.

If I understand correctly you have two virtual phys going to a single 
wpan interface
e.g.
phy0 -> wpan0
phy1 -> wpan0

My setup is two separate transceivers. Each with its own phy and wpan 
interface.
e.g.
phy0 -> wpan0
phy1 -> wpan1
