      Description

      reactos-bootcd-0.4.14-dev-115-g4576127-x86-gcc-lin-dbg

      ACPI HAL:
      works fine.

      Standard HAL, Stage 3:

      (ntoskrnl/mm/ARM3/sysldr.c:176) Loading: \SystemRoot\System32\win32k.sys at ... with ... pages
      (ntoskrnl/mm/ARM3/sysldr.c:176) Loading: \SystemRoot\System32\ftfd.dll at FC59D000 with 12f pages
       
      *** Assertion failed: TempPte.u.Hard.Valid == 1
      ***   Source File: /srv/buildbot/worker_data/Build_GCCLin_x86/build/ntoskrnl/mm/ARM3/sysldr.c, line 2412
       
      Break repeatedly, break Once, Ignore, terminate Process or terminate Thread (boipt)?
      kdb:> o
      Execute '.cxr FC9B5544' to dump context
       
      Entered debugger on embedded INT3 at 0x0008:0x809564e2.
      kdb:> bt
      Eip:
      <ntoskrnl.exe:1564e3 (sdk/lib/rtl/i386/debug_asm.S:34 (DbgBreakPoint))>

      Couldn't access memory at 0xFC9B584C!
      

      For what it's worth,
      this assertion is triggered on ftfd.dll (1st) or win32k.sys (2nd):
      can't tell which one (or both) until reproduced (with a custom log)...
