Hello
Since few days I have supported by OpenBSD's drivers Wifi card. CPU is dual core. System:

Code:

# sysctl kern.version                                                                                                      
kern.version=OpenBSD 6.0-current (GENERIC.MP) #85: Wed Dec 28 23:42:44 MST 2016
    build@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
# dmesg | grep iwn                                                                                                         
iwn0 at pci3 dev 0 function 0 "Intel Centrino Advanced-N 6200" rev 0x35: msi, MIMO 2T2R, MoW, address <censored>

I have also checked bsd.sp kernel.

When I am scanning for Access Points using command:

Code:

ifconfig iwn0 scan

system freezes. I can not move cursor in Xorg. Music playback stops until ifconfig command ends. I have used time command to measure elapsed time and it is usually around 3 seconds.
After Wifi scanning ends everything seems ok.
