Seems to be a kernel problem then, so re-assigning.

Thanks.

My report appears to be a duplicate of #611551. There are a total of
four EeePC's reported (Hans, Domenico * 2, and myself).

Just for grins I tried a few things:

pm-hibernate works on another desktop system (wasn't even aware that
it had been configured, nice!) - resume works, even with tainted
nvidia driver. [amd64, up-to-date squeeze, etc.]

Tried hibernate on EeePC with X unloaded, and again with rescue mode
(X never loaded), resume still fails in each of these cases.

Looks an awful lot like this is EeePC specific.

Default Bug#611750: Asus EeePC resume from hibernation fails

I downgraded to linux-image-2.6.32-5-686_2.6.32-29_i386.deb¹ and resume
From hibernate works flawlessly again.

Could the bug be caused by one of these changes in ..-30?

* drm/i915: Free hardware status page on unload when physically
mapped.
* drm/i915/overlay: Ensure that the reg_bo is in the GTT prior to
writing.
* drm/i915/sdvo: Always add a 30ms delay to make SDVO TV detection
reliable.

Looking over the debian changelog, nothing else pops out as being
something this model of EeePC uses - exec or tty changes perhaps?

I rebuilt -30 with these three patches disabled:

debian/patches/series/30:
#+ bugfix/all/drm-i915-free-hardware-status-page-on-unload-when-physically-mapped.patch
#+ bugfix/all/drm-i915-overlay-ensure-that-the-reg_bo-is-in-the-gtt-prior-to-writing.patch
#+ bugfix/all/drm-i915-sdvo-always-add-a-30ms-delay-to-make-sdvo-tv-detection-reliable.patch

Hibernate/resume is working.

Will try building with fewer patches disabled to isolate which patch is
breaking EeePC resume.

I tried another build with only one patch disabled:
drm-i915-free-hardware-status-page-on-unload-when-physically-mapped.patch
…resume fails again.

I suspect the bug is triggered by:
drm-i915-overlay-ensure-that-the-reg_bo-is-in-the-gtt-prior-to-writing.patch

I'll do another build with only that patch disabled in a few hours.

Tested -30 kernel built with only having patch
drm-i915-overlay-ensure-that-the-reg_bo-is-in-the-gtt-prior-to-writing.patch
dropped and resume from hibernate works.

The patch is described as:

Just makes sure that writes are not being aliased by the CPU cache and
do make it out to main memory.

Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

I followed the bugzilla link, the bug is about a green window shown
instead of video - I have no such problem on this hardware (945GM)
without the patch (tested command: mplayer 1259_X_in_squeeze.ogv -vo
xvort=88).

BTW, looks like this my bug report may also be a duplicate of #610589
and that Sebastian Andrzej Siewior has reported a similar regression
with this patch (however EeePC immediately resets during resume). That
makes 5 or 6 accounts of i915 hardware with broken hibernate/resume on
-30 kernel.

Thanks Gerald for your investigation. I'm also hit by this bug
(my Asus 1002HA is rebooting when trying to resume from hibernation) !

I'm using Samsung N150, problem still exists: sometimes system wake up
correctly, sometimes with instant reboot after finishing resume.

Hello,

Perhaps you're hit by same bug as me, see Debian bug #622259, and
suggested patch.If you can test it, please report if it fixes your
problem.

Fred.

Do you mean removing patch
x86-hotplug-use-mwait-to-offline-a-processor-fix-the-legacy-case.patch
?

I've found that kernel sources linux-2.6_2.6.32-33 don't have this
patch, is it ok or patch was renamed/updated?
