KERNEL_DATA_INPAGE_ERROR (7a)
The requested page of kernel data could not be read in.  Typically caused by
a bad block in the paging file or disk controller error. Also see
KERNEL_STACK_INPAGE_ERROR.
If the error status is 0xC000000E, 0xC000009C, 0xC000009D or 0xC0000185,
it means the disk subsystem has experienced a failure.
If the error status is 0xC000009A, then it means the request failed because
a filesystem failed to make forward progress.
Arguments:
Arg1: fffff6fc40006168, lock type that was held (value 1,2,3, or PTE address)
Arg2: ffffffffc0000185, error status (normally i/o status code)
Arg3: 00000000a6ff1860, current process (virtual address for lock type 3, or PTE)
Arg4: fffff88000c2d008, virtual address that could not be in-paged (or PTE contents if arg1 is a PTE address)
