I don't have the older kernel config anymore, but it was pretty the 
same, as my current one.
I've now done some tests and it's quite interesseting. Kernelversion did 
not matter for me.

Running with current firmware-5.bin, it's always crashing. I tried 
different BIOS options, nothing helped.

BUT: Downgrade to firmware-2.bin helps.
ath10k_pci 0000:03:00.0: firmware ver 10.1.467.3-1 api 2 features 
wmi-10.x, has-wmi-mgmt-tx,no-p2p crc32 2c3ffc2f

Running such old firmware, the Wifi just runs stable. NO firmware crash 
happens. When I just change firmware back to firmware-5.bin, it crashes 
again.
So there seems to changed something. Can be this debugged somehow?

With firmware-2.bin, I am also getting such errors, but WiFi works fine:
[   82.504901] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 0, skipped 
old beacon
[   82.556103] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 1, skipped 
old beacon
[   87.113085] ath10k_warn: 89 callbacks suppressed

Currently, the workaround is for me firmware-2.bin, but IMHO it's not a 
solution..
Any Ideas?

Cheers
Conrad
