Re: syscons problem in ddb, if_afdata initialization (was: Re: 5.3-BETA3 , panic, probably IPv6+SMP+mpsafenet related)

FYI, I've got exactly same panic even after your patch committed.
(and debug.mpsafenet=0)
This box runs stock -CURRENT of some days ago.
And I don't much care about panicing this system.
Please feel free to ask to do tests. :-)
