Yes, okay, that is indeed totally separate.  You should bring that
issue up with Bob Moore and Len Brown on the linux-acpi mailing list.


The Debian bug for this one is <http://bugs.debian.org/680707>.
Please cc me or 680707@bugs.debian.org if bringing it up with ACPI
folks so we can track the discussion.


Jonathan, so I decided to continue the discussion of the wakeup-lockup
bug here, so I can Cc: 680707 and the commit author. I have adjusted
the subject to the new subject you stated in the cloned Debian bug.

I removed Ben Hutchings and Alan Stern from the Cc. Please feel free
to add them back.

Hello, Bob!

This is a follow-up email on Debian bug 680707.

I am experiencing lock-ups in my machine. You will notice the bug
initially refers to a different problem. That's because this bug
was discovered by accident on my machine, while testing for a
different suspend bug with a newer kernel version.

The problem is a full system lock-up on resume. The HD led stays on.
The 5-sec power-button cycle isn't enough to get the system back.
It requires a full mechanical power cycle from the power supply.

I bisected the problem as requested by Alan Stern, and tracked it
down to the following commit:

commit 2feec47d4c5f80b05f1650f5a24865718978eea4
Author: Bob Moore <robert.moore@intel.com>
Date:   Tue Feb 14 15:00:53 2012 +0800
ACPICA: ACPI 5: Support for new FADT SleepStatus, SleepControl registers 

    Adds sleep and wake support for systems with these registers.
    One new file, hwxfsleep.c

There is already some information already captured in the Debian
bug log.

Is there anything I can do to help get this fixed?

Thanks!!
