BugCheck A, {fffffc604b3fa980, 2, 1, fffff80002897cf9}
Probably caused by : memory_corruption ( nt!MiUnlinkPageFromLockedList+6c9 )
IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: fffffc604b3fa980, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002897cf9, address which referenced memory
