Hi Emmanuel,
Your patch "iwlwifi: mvm: BT Coex - disable BT when TXing probe request
in scan" fixed wifi dropping on my 7260 with scan time outs but now my
Bluetooth mouse freezes and unfreezes as it gets re-detected every few
minutes (3.14-rc2+):

Is there a better fix in the works? Any workaround? 802.11g performance
also looks to be subjectively poorer with Bluetooth on than without.
Regards,
David.
