Bug 11886

Summary:	without serial console system doesn't poweroff
Product:	Power Management	Reporter:	Daniel Smolik (marvin)
Component:	Other	Assignee:	power-management_other
Status:	CLOSED INSUFFICIENT_DATA
Severity:	normal	CC:	alan, rjw, yakui.zhao
Priority:	P1
Hardware:	All
OS:	Linux
Kernel Version:	2.6.27.4	Subsystem:
Regression:	Yes	Bisected commit-id:
Bug Depends on:
Bug Blocks:	11167
Attachments:	kernel config

Description Daniel Smolik 2008-10-29 04:06:11 UTC

Latest working kernel version:
Earliest failing kernel version:2.6.27.2
Distribution: Debian Etch
Hardware Environment: Supermiro C2SBC-Q  Dual Core Intel Cpu 1G RAM
Software Environment: Debian Etch
Problem Description: If I does't add serial console to kernel command line system doesn't poweroff. Linux hangs there:

e1000e 0000:0d:00.0: PCI INT A disabled
e1000e 0000:00:19.0: PCI INT A disabled
ACPI: Preparing to enter system sleep state S5
Disabling non-boot CPUs ...

If I disable in kernel config Suspend to Ram and Hibernate all works without console. But with Suspend and hibernate enabled and serial console  added to kernel cmd line all works too:

e1000e 0000:0d:00.0: PCI INT A disabled
e1000e 0000:00:19.0: PCI INT A disabled
ACPI: Preparing to enter system sleep state S5
Disabling non-boot CPUs ...
CPU 1 is now offline
SMP alternatives: switching to UP code
CPU1 is down
Power down.
acpi_power_off called

Steps to reproduce:
Compile kernel with attached config and try poweroff without serial console.

Created attachment 18494 [details]
kernel config

With this kernel config system doesn't poweroff.

OK, this is weird.

But the good news is that there is a very small number of commits
between 2.6.27.2 and 2.6.27.4.

ftp://ftp.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.27.3
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.27.4

I'd be looking at these:

commit 3b987ac961486373f91191b14291b331fa546072
Author: Rafael J. Wysocki <rjw@sisk.pl>
Date:   Sat Sep 6 13:13:01 2008 +0200

    ACPI suspend: Always use the 32-bit waking vector
    
    commit a6629105dd03d370fcb31e97bddf223fa4bb651e upstream.


commit 66036f5862883fcc9f7ff8550685a5a3de1a57e4
Author: Rafael J. Wysocki <rjw@sisk.pl>
Date:   Sat Oct 4 00:05:05 2008 +0200

    ACPI Suspend: Enable ACPI during resume if SCI_EN is not set
    
    commit d0c71fe7ebc180f1b7bc7da1d39a07fc19eec768 upstream.



presumably 2.6.28-rc3 is also broken?

I don't know I can test it on Thu. But may be may fault or misunderstanding fist kernel which I test is 2.27.2. I don't 
test any kernel before. I don't know if 2.6.26 works.

Sorry, I compile kernel but still didn't test. I try it on Monday.

I today test 2.6.26 and it works OK.

OK

Please check if this commit helps
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8d00450d296dedec9ada38d43b83e79cca6fd5a3

If not, the fastest way to find the failing commit would probably be to carry
out bisection of kernels between 2.6.26 (good) and 2.6.27 (presumably
bad as well as 2.6.27.2).

I start bisecting please wait a little.

Comment 12 Daniel Smolik 2008-12-11 12:21:04 UTC

Tested on different HW and 2.6.27.6 and problem still exists.

Comment 13 Mark Lord 2008-12-20 18:42:53 UTC

Mmm.. I wonder if this is related to the occasional "won't power off" bug I see with SMP in 2.6.27.xx ?

The presence of a serial console means that things will happen more slowly, as the kernel pauses to ensure the console message bytes are slowly transmitted out over the serial.  This would affect timing of races and the like, and might "make things work" by accident.

Mmm..

Comment 14 ykzhao 2009-09-29 07:09:07 UTC

Hi, Daniel
    Will you please try to confirm whether the issue still exists on the latest upstream kernel?
   Please also attach the output of lspci -vxxx, acpidump.
   Thanks.
