ath11k-qca crashing

[André Eberle]

Hello,

I have been using the ath11k wireless driver (qca version ie. QSDK) in
a IPQ807x router, but I am facing crashes. Ethernet and WAN work fine.
I can connect to WiFi, and receive an address from DHCP. I can even
send/receive a number of packets via the wifi nic, but if I try to,
say, send/recv a larger number of packets at once (like visiting a
webpage), the kernel crashes. I have been digging into the NSS and
ath11k drivers trying to isolate the problem, but so far my debugging
attempts have failed. I have so far failed to set up kgdb on qsdk
also, so no help on that front.

What is the best way to debug the ath11k drivers for such problems? Or
at least try to determine if the crashes are from the driver, or
elsewhere in the NSS system?
