Did some futher testing to exclude problems....
The wlan0 and eth1 are both part of a bridge. I have removed the eth1 
interface so the the eth1-driver cannot interfer with the ath9k driver.
Also no result. The server still locks.

What is the right way to combine the eth1 and wlan0 into a bridge. Do I even 
need  a bridge? The hostapd.config says I must define a bridge when I use the 
nl80211driver interface.
The bridge has an IP adress, wlan0 and eth1 are in the same subnet.

When hostapd is started I have some error-messages. Dont know if they can 
hurt...
Failed to set CTS protect in kernel driver
Failed to set Short Slot Time option in kernel driver
Could not set preamble for kernel driver
