Our kernel is 3.10. We would like to add parallel support for ath10k_pci from backports. However after inserting compat.ko, cfg80211.ko and mac80211.ko from backports, 8192cu.ko and 8821au.ko terminate with following message: [ 512.188364] 8192cu: Unknown symbol wiphy_new (err 0) [ 512.188481] 8192cu: Unknown symbol cfg80211_send_disassoc (err 0) [ 512.188554] 8192cu: Unknown symbol cfg80211_send_rx_assoc (err 0) [ 512.188607] 8192cu: Unknown symbol cfg80211_inform_bss_frame (err 0) Those interfaces are exported when I load cfg80211.ko compiled from kernel 3.10. But I can not see them in cfg80211.ko provided by backports. Do you know this problem ? Is there any easy way to solve this issue ? BR Bartek
