QCA988X: FW firmware-5.bin_10.2.4.70.63-2 crashes at ath10k load

Sun Sep 17 13:08:58 PDT 2017

Hi,

I am using a BT Home Hub 5A with LEDE and backports-4.14-rc1 + some
patches from the LEDE repository. It has one QCA988X card in it which
works like expected with FW firmware-5.bin_10.2.4-1.0-00029, but crashes
with FW firmware-5.bin_10.2.4.70.63-2.

Both files are taken from the ath10k-firmware repository and I am using
the same board.bin file. I also saw the same crash with the older
mac80211 from January currently shipped in LEDE.

Log from crash with FW firmware-5.bin_10.2.4.70.63-2:
