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.

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).
