failed to set kickout threshold on vdev 0: -11

[Conrad Kostecki]

Hi!
I am having some problems with my two ath10k card since kernel 4.0..

After booting a fresh system, I am unable to start hostapd, as it fails 
to start up the cards:

[ 3529.630065] ath10k_pci 0000:07:00.0: failed to set kickout threshold 
on vdev 0: -11
[ 3529.630076] ath10k_pci 0000:07:00.0: failed to set vdev 0 kickout 
parameters: -11
[ 3538.630064] ath10k_pci 0000:07:00.0: could not suspend target (-11)
[ 3696.390142] ath10k_pci 0000:0c:00.0: failed to set kickout threshold 
on vdev 0: -11
[ 3696.390153] ath10k_pci 0000:0c:00.0: failed to set vdev 0 kickout 
parameters: -11
[ 3705.390129] ath10k_pci 0000:0c:00.0: could not suspend target (-11)

After trying again 2-3 times, it's starting working and hostapd is 
starting up.

OS: Gentoo
Kernel: 4.0.1
ath10k_pci 0000:0c:00.0: qca988x hw2.0 (0x4100016c, 0x043202ff) fw

What's going on? Anybody some ideas?

Cheers
