Huh, interesting.  I didn't think the kernel bugzilla was visible to
search engines (I wish it were).  But maybe Google just found an email
that mentioned the URL?

Can you post a complete dmesg log including a lid close/event cycle?

Bug 57961 is for ExpressCard changes that we didn't handle correctly.
It doesn't sound like you're adding or removing an ExpressCard, so
you're likely seeing a different problem.

Is the problem that (1) you see "_handle_hotplug_event_root Bus check
notify on \_SB_.PCI0" messages that you don't expect, and (2) you do
not see LID events, which you do expect?

Is there anything that is not actually working correctly, or is it
just messages that don't seem right?
