Summary: without serial console system doesn't poweroff
Product: Power Management
Version: 2.5
KernelVersion: 2.6.27.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: power-management_other@xxxxxxxxxxxxxxxxxxxx
ReportedBy: marvin@xxxxxxxxxx


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.

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.

I'd be looking at these:

commit 66036f5862883fcc9f7ff8550685a5a3de1a57e4
Author: Rafael J. Wysocki <rjw@xxxxxxx>

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.
Can you try 2.6.26, please?
Yes, no problem.

And did it work?

Rafael
I today test 2.6.26 and it works OK.
