SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)
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.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff88005ab5fc6, The address that the exception occurred at
Arg3: fffff88003cc7758, Exception Record Address
Arg4: fffff88003cc6fb0, Context Record Address
