ACPI breakage (Re: 2.6.19-rc6: known regressions (v2))

I do not know if this is related, but testing one of my laptops (always a 
good idea to check the week before release) shows that my trusty old 
Compaq N620c locks up rather quickly at boot with the current -git tree. 

Total lockup - no sysrq, no messages, no nothing.

I've mostly bisected it (what the _hell_ did we do before "git bisect"?), 
and right now I know:

commit 9aaed2b42d00d4abb2748d72d599a8033600e2bf is bad (that's Len's "pull 
trivial into test branch") commit.

v2.6.19-rc2 seems all good.

Which leaves a chunk of just a few ACPI commits left to bisect. 

I'll do five or so more reboots, and I should be able to tell exactly 
which commit breaks. It almost always locks up very early during boot 
(generally during the "initializing udev" phase), although sometimes it 
survives a bit further..

Dammit.

It looks like 37605a6900f6b4d886d995751fcfeef88c4e462c, and I should have 
realized that immediately.

That commit re-introduces the bug that we already reverted once.

Why the hell did that idiotic thing go in, when we had to revert it once 
already (see commit 72945b2b90a5554975b8f72673ab7139d232a121 for the 
earlier revert).

It was broken then, it is broken now. Nothing has changed.

Why did you guys try to sneak it in again? Last time this same "use a 
second workqueue" patch went in (in a different form), we had _exactly_ 
the same problems, with total lockups, and way too high CPU usage.

The bugzilla entry that you refer to in that commit is even the same one 
that discussed why the _original_ patch was totally broken.

It's even the same AUTHOR who wrote the original buggy patch, that pushed 
through the same buggy patch AGAIN.

Dammit, this is frustrating.

Why did people expect it to suddenly not be buggy?

I've not seen this in over 3 days now, and am willing to believe that
the previous instance (after manually reverting the patch identified
by Linus) was a fluke ... it's certainly not the critical/blocking kind
of issue it had previously been.
