crash on resume after suspend

crash on resume after suspend

[Loke Bharti]

Hi. I am using xen 4.2.2, the system runs okay. But when I suspend it, it does so, but crashes on trying to resume.
Here is lsmod output:

Hey,

Could you be a bit more specific please? Is this the guest?
The host? How does it crash? Do you have a serial console with
its output?

ACPI S3 resume with Xen and Linux not working (will work in Linux v3.11) Was: Re: Re: crash on resume after suspend

ACPI S3 resume is not yet working (but will with Linux 3.11) b/c the
patches to allow that functionality had not been merged upstream.

Hi Konrad,
Do you imply your own tree(which branch?)
 (http://git.kernel.org/cgit/linux/kernel/git/konrad/xen.git)
 can work with Dom0 S3?
Where are the patches to support Dom0 S3? I'd like to try them.
I see there is a branch devel/acpi-s3.v10 in the tree, but I'm not sure if you meant it.

Thanks,
-- Dexuan

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git linux-next  or bleeding-edge

You want to make sure these show up

068e0dc xen / ACPI / sleep: Register an acpi_suspend_lowlevel callback.
d6a77ea x86 / ACPI / sleep: Provide registration for acpi_suspend_lowlevel.

Hi Konrad,
Thanks for the information!

I'm using Xen-4.2.1 + Linux 3.8.8 and Dom0 S3 has such an issue:

Afaik for ACPI S3 to work you need Xen 4.2.3 (so currently 4.2.2 + a couple of patches from stable-4.2 branch):

http://xenbits.xen.org/gitweb/?p=xen.git;a=shortlog;h=refs/heads/stable-4.2

These are the post 4.2.2 fixes for ACPI S3:

Not sure if your issue is related to those missing hypervisor patches.. worth checking.

The first is necessary, the second is not.

However, linux 3.8.8 will not work out of the box - you need to apply
the changes Konrad pointed out, or else the machine will go to sleep,
but never wake up.

Hi Ben, Pasi, thank you both very much for the info!

Next week, I'll try the latest xen 4.2 stable repo and latest upstream
Linux 3.9.8 plus the 2 commits((or more?) Konrad pointed out.
I hope it can work, then I can port the related patches to my specific
Xen/linux versions(I have to use the versions for some reason).

Thanks,
-- Dexuan

FYI:
My xen 4.2.1 + picking the following 3 commits can make Dom0 S3 work:
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=2ea6abb8e60cf557b20b8a9904deb73433103d9b
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=77cb78851429a5a8509e3dfed466b2580ad5c60d
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=7fe762b3f06f0e81ce5b3456dc61fc004562ef21
(Surely I also need to apply the 2 commits mentioned by Konrad to my Linux 3.8.8).

Thanks,
