PFN_LIST_CORRUPT (4e)
Typically caused by drivers passing bad memory descriptor lists (ie: calling
MmUnlockPages twice with the same list, etc). If a kernel debugger is
available get the stack trace.
Arguments:
Arg1: 0000000000000007, A driver has unlocked a page more times than it locked it
Arg2: 00000000000162bf, page frame number
Arg3: 020002700027edc0, current share count
Arg4: 0000000000000000, 0
