Hi!

(Added myself to CC, because I'm not subscribed)

with linux-next snapshot 20080604 my Laptop morphes into sitting duck
and I think this is due to this:

I assume 2.6.26-rc5 is OK?

Indeed.. just tried it with (nearly) the same config: no unable to locate
IOAPIC

Will try todays next snapshot above -rc5 now.

OK, thanks.

It would be great if you could test 2.6.26-rc5 plus
http://userweb.kernel.org/~akpm/git-acpi.patch.  That'll allow us to
confirm that the regression is due to changes in the acpi tree.

Sorry for the delay.. real-life you know ;)

I guess you'd expect me to confirm the behavior on rc5 with this patch aplied, 
but .. well this Kernel works!

So I think the regression is NOT in the acpi tree. Perhaps pci subsystem?

There is behind-the-scenes finger-pointing going on ;)

I don't think we know what caused this regression, sorry.

If I find time I'll try bisecting it..

That would be fantastic, thanks.  Please don't let us merge this
regression into 2.6.27.  We have a few weeks.
