I downloaded all snapshot kernel from December and did some reboot ->
download -> repeat loops and found that the last working kernel where I
get full speed with my AP is the following:

OpenBSD 6.2-current (GENERIC.MP) #265: Sat Dec  9 10:24:12 MST 2017

With the kernel from Dec 12 on download takes forever.

@Stefan:  Since I saw you quite often in the commit logs at that time
... any idea what's happening here?

Cheers
