Since I have updated to Windows 10, my 8" tablet, a Dell Venue 8 Pro has random BSODs while in connected standby or normal usage, mostly ever 2-4 days. I did several clean installs already, tested the RAM, latest BIOS, all latest drivers, nothing helped. Here is a WinDBG output of the latest minidump file:

You can troubleshoot most symbol related issues by turning on symbol loading diagnostics (!sym noisy) and repeating the command that caused symbols to be loaded.
You should also verify that your symbol search path (.sympath) is correct.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
happening.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: 994b1f4e, The address that the exception occurred at
Arg3: 922fb978, Exception Record Address
Arg4: 922fb540, Context Record Address

I guess the problem has to do with ar6knwf81.sys which is the wifi/bluetooth driver, Any idea how to fix this?

The Qualcomm Atheros Adapter driver needs to be updated -- if you can find an update. It usually is very difficult to find driver updates for Atheros. as they don't keep their drivers maintained like others do (Intel, Realtek).

Check your system manufacturer's support site.

Also try:
Official site: https://www.qualcomm.com/drivers
Unofficial site: https://www.atheros.cz

Nice job with Windbg.
