Page Fault for QCA6174
I running QCA6174 with FreeBSD RELEASE 12.0 on my laptop, after load the driver the page fault error occurred.
I try to replace the board data based on issues https://github.com/erikarn/athp/issues/20 , but the issue still exist.
Does anyone have an idea for this issue? I need some help.

After change the board data from the https://github.com/kvalo/ath10k-firmware/blob/master/QCA6174/hw3.0/board.bin , loading the driver work.
Now the issue is when I create the wlan interface by using command "ifconfig wlan0 create wlandev athp0" , the system panic , I need some help, plz.

Hello, i can confirm i have exactly the same problem, a panic due to a mutex, on FreeBSD current
Sorry I did not read the entire post we are currently working on mutex issues.
Hi Geramy,
Freebsd 12 running on thinkpad t400
The attached is my note.
Thanks.

i have an older razer blade 2015 model the QCA6174 is branded as "killer networking" wireless card
hi! Does anyone have the exact models of their cards? Even the FCC IDs stamped on them would be nice.
There are a handful of QCA6174 variants out there and they have different data path / command path needs.
I've fixed one bug in the RX path that caused a panic on my QCA6174 HW3.2, but there are other NICs out there and other bugs to chase.
I'd like to try and fix them all but I will need more NICs to test! Thanks!
@erikarn just compiled your module (cheating on the MA_OWNED undefined in my case).
Here is the dmesg when i load the if_athp after compilation:

i just cheated again, adding the new modules and replacing firmware-5 with firmware-6 (which exists not the first) in the code. you have a PR adding the missing parts here: https://github.com/erikarn/athp/pull/36 Now i have a better dmesg output but no network card appear in ifconfig:

hi! Does anyone have the exact models of their cards? Even the FCC IDs stamped on them would be nice.
There are a handful of QCA6174 variants out there and they have different data path / command path needs.
I've fixed one bug in the RX path that caused a panic on my QCA6174 HW3.2, but there are other NICs out there and other bugs to chase.
I'd like to try and fix them all but I will need more NICs to test! Thanks!

please do throw patches at me, I'm tidying up the tree right now in an attempt to get it ready to land.
