If a kernel debugger is available get the stack trace. Arguments: Arg1: 0000000000000099, A PTE or PFN is corrupt Arg2: 00000000002bdd6e, page frame number Arg3: 0000000000000000, current page state Arg4: 00000000002bddee, 0 I've got a quick question, page states can be of three things: free, reserved and committed. So with a Stop 0x4E bugcheck, which numbers correspond to what page state? For example, what page state is 0?
