ath10k: freeze after disconnection on killer1525

Mon May 11 05:50:44 PDT 2015

Hi,
I'm using a Killer 1525 with hw2.1 firmware, and sometimes it stop working.
I can get it working again disconnecting and reconnecting, but sometimes
on disconnection it freezes for a long time:

When it freezes, I can't use any command like ifconfig, iwconfig,
ethtool (they sit there until the freeze ends, ctrl+c is useless).
I can't even rmmod the ath10k_pci. After about a minute, it works again
and the freezed commands are executed.
