Parameter 3 contains the page CRC value. Parameter 4 contains the expected CRC value. The page table and PFNs are out of sync. Parameter 2 is the expected PTE. The caller is unlocking a system cache address that is not currently locked. This address was either never mapped or is being unlocked twice.

This action would cause a conflicting hardware translation buffer entry, and so it was refused by the operating system. Since the caller specified "bug check on failure" in the requesting MDL, the system had no choice but to issue a bug check in this instance.

The caller is unlocking a pageable section that is not currently locked. This section was either never locked or is being unlocked twice. A driver tried to map a physical memory page that was not locked. This is illegal because the contents or attributes of the page can change at any time.

This is a bug in the code that made the mapping call. Parameter 2 is the page frame number of the physical page that the driver attempted to map. The caller specified an MDL that contains an unlocked or invalid physical page. Parameter 2 contains a pointer to the MDL. Parameter 3 contains a pointer to the invalid PFN.

Parameter 4 contains the invalid PFN value. It is illegal for callers to build an MDL for a virtual address range that is not resident. In the process of performing a write, the referenced virtual address is mistakenly marked as copy on write. Parameter 2 is the FaultingAddress. Parameter 3 is the PTE contents. Parameter 4 indicates the virtual address space type. All the page table pages of an exited process could not be deleted due to outstanding references.

A cached kernel stack was corrupted while on the freelist — this memory corruption indicates a serious problem of which the calling stack may be a victim or a culprit. A driver tried to write to an unallocated address in the user space of the system process.

Parameter 2 contains the address of the attempted write. The allocation bitmap is corrupt. The memory manager is about to overwrite a virtual address that was already in use. This can be the result of a write-after-free bug in a driver, or an overrun from a previous page. Parameter 2 contains the address of a free pool block. Parameter 4 contains the value that was expected to be at that address.
