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: fffff805802b1699, The address that the exception occurred at
Arg3: fffffc89cac5a458, Exception Record Address
Arg4: fffffc89cac59c90, Context Record Address
Debugging Details:
------------------
Press ctrl-c (cdb, kd, ntsd) or ctrl-break (windbg) to abort symbol loads that take too long.
Run !sym noisy before .reload to track down problems loading symbols.
