BugCheck A, {83dfffec, 2, 1, 82ed7178}

Probably caused by : memory_corruption ( nt!MiReplenishPageSlist+69 )


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: 83dfffec, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, 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: 82ed7178, address which referenced memory
