Subject: s2disk: potential problems with HPA host protected area

I got a bug report in the debian BTS which is beyond my knowledge. 
Could one of you shed some light on the issue?



Forwarded message:

Machine: IBM Thinkpad R50p

I recognized following issues concerning s2ram/s2disk/s2both:

  - calling s2ram works fine, resuming from RAM works
  - after having resumed and calling s2disk the machine hangs with 
    heavy HD load
  - it's not possible to terminate or kill any process with SysRq+E/I
  - following messgages appears again and again if SysRq+E is pressed:

  hda: task_out_intr: status=0x51 { DriveReady SeekComplete Error }
  hda: task_out_intr: status=0x10 { SectorIdNotFound }, \ 
  LBAsect=110561486, sector=110561486
  hda: failed opcode was: unknown

  where 'LBAsect' and 'sector' will have values above 11000000 each 
  time the behaviour is reproduced

After having disabled the so called "IBM Predesktop Area" in the BIOS
everything works (in the BIOS setup: Security -> IBM Predesktop Area ->
Current Setting: Disabled).
As far as I know this IBM Predesktop Area is located in a HPA.
I'm not sure, if this is really a bug (and if so, if it is related to
Hope anyone will find out.
