Probably restoring the machine from the recovery CDs will restore everything so it can be reproduced.

So Daniel won't be able to reproduce this anymore... is that correct Daniel? This is correct. I'm not able to reproduce this anymore. As Stefan has already stated, I would have to start the IBM recovery tool or get the recovery cd. If the problem is just related to the HPA, then I could try to setup such an area again. Anyone an idea how to manage that? I will have a novell bugzilla report number about this soon.

Hi,
I got a bug report in the debian BTS which is beyond my knowledge.
Could one of you shed some light on the issue?
Hopefully.
I ran across exactly the same on a T42p today.
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 1100 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
uswsusp).
It is not related to uswsusp, it is related to suspend to ram. The kernel
disables the HPA on boot. The harddrive is power cycled during suspend to
RAM. After resume, HPA is not disabled again. = boom.
You can verify this with:
- hdparm -I /dev/hda /tmp/identify-before
- s2ram
- hdparm -I /dev/hda /tmp/identify-after
then diff identify-before and identify-after, the disk will report different
sizes.
Unfortunately, once the Predesktop Area was disabled, you cannot reenable
it, so the bug is only reproducible until the fix with disabling the hpa
is made.
I will have a novell bugzilla report number about this soon.

As far as I know this IBM Predesktop Area is located in a HPA.
Which is where?
I'm not sure, if this is really a bug (and if so, if it is related to
uswsusp).
Hope anyone will find out.
If this is a bug, it is a kernel one, I think.
