Dear Kalle, To add to this issue: The suspicion is that either the BDF or the CAL syntax might have changed as the firmware crashes really early (5 seconds after load), so I tried the BDF released on codelinaro for FW 2.7, and that yields the same crash. Note that if I use the same 2.7 BDF with FW 2.5, there is no crash. As FW 2.5 runs perfectly fine on the same HW, kernel and ath11k revision where FW 2.6 and 2.7 crashes, everything points towards a FW / BDF / CAL interoperability or some sort of syntax related issue. If someone from QCA can take a look at the BDF and CAL of the device, that would be a big step forward. Maybe a flag or two needs to be changed. Note that the device's current BDF and CAL was generated with template 5.0.5, so fairly old. Please let me know and I can attach both files. If any more information is needed, I am happy to help.
