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 - Simon On 16/05/15 16:33, Alexander Aring wrote: > Hi Simon, > > On Fri, May 15, 2015 at 04:02:32PM +0100, Simon Vincent wrote: >> I tried the solution you proposed but it did not work, it resulted in a >> kernel crash (bad paging request). >> > I can now reproduce your issue when I am using the fakelb driver _with_ > xmit_sync callback and two vitual phys. > > I tried my patch and it's working fine afterwards, can you please check > if the "kernel crash (bad paging request)" isn't another issue or > something failed while applying the diff? > > Can you check that again?
