Description W. Michael Petullo 2011-03-30 16:02:13 UTC

Description of problem:
Power management does not seem to work when the kernel is running in Xen Dom0. For example, "pm-suspend" does not suspend my system. Instead, the system merely becomes unresponsive.

The kernel also does not power down my system when I run shutdown. The last things that is printed to the console is:

Halting system...
[7962.081194] Power down.
-

The system "halts" but does not power down.

Version-Release number of selected component (if applicable):
kernel-2.6.38-1.fc15.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Boot kernel in Xen Dom0
2. Attempt to run "pm-suspend"
3. Reboot and attempt to shutdown
  
Actual results:
System hangs

Expected results:
System should suspend or power off

Patches posted: http://comments.gmane.org/gmane.linux.acpi.devel/50701

but need some work before they are going to be accepted upstream.

Comment 2 Konrad Rzeszutek Wilk 2011-09-29 21:03:39 UTC

Patches posted (v2) https://lkml.org/lkml/2011/9/29/408

the Tboot maintainer acked them.

These are still working towards inclusion for the 3.2 release.  I don't see us backporting them to F15 at this time.  I'm going to move this bug to rawhide, where we'll see them show up naturally when it gets rebased.

Konrad, if you have an alternative suggestion please let me know.

Comment 4 Josh Boyer 2012-02-22 15:56:42 UTC

I believe we're on v4 now, but still not included in linux-next or Linus' tree:

Comment 5 Konrad Rzeszutek Wilk 2012-03-23 21:02:38 UTC

Yeah, some patches for the support are trickling in.

Comment 6 Fedora End Of Life 2013-04-03 15:36:16 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Comment 7 Konrad Rzeszutek Wilk 2013-09-09 14:09:43 UTC

And just in case folks are curious - the patches are in v3.11.
