On a Thinkpad T41 (people have also reproduced this on a T40), waking up from an S3 suspend-to-ram causes no further acpi interrupts to be generated, thus making acpid not catch any more events. This bug is similar, but not the same, as #1199, #1409, and #1415.
Did you try patch at http://bugzilla.kernel.org/show_bug.cgi?id=1661

This bug should be reopened. It's a totally different issue than 1661, especially since the patch which fixes that bug does not fix this one.
closing bug, just merging into 1661. *** This bug has been marked as a duplicate of 1661 ***
