 Well I never meant it to be merged, but Andi picked it up from Bugzilla
bug #3927, added some bugs of his own, then sent it on.

 This bug was mine, though: just checking for vendor == ATI was a bad idea.
Current earlyquirk code actually looks at PCI bridges instead of host bridge,
so to get an accurate test I guess it needs to look at PCI dev 00:00.0 and
check both vendor and device ID.  As new models come out they will have to
be added one by one.

 With a real understanding of what's going on maybe this problem can be solved
reliably with generic code, but it's beyond me...

"Read my lips: no more merges" - aka Linux 2.6.14-rc1

[Linus Torvalds]

Ok, it's been two weeks (actually, two weeks and one day) since 2.6.13, 
and that means that the merge window is closed. I've released a 
2.6.14-rc1, and we're now all supposed to help just clean up and fix 
everything, and aim for a really solid 2.6.14 release.

Both the diffstat and the shortlog are so big that I can't post them on 
the kernel mailing list without getting the email killed by the size 
restrictions, so there's not a lot to say. 

alpha, arm, x86, x86-64, ppc, ia64, mips, sparc, um.. Pretty much every
architecture got some updates. And an absolutely _huge_ ACPI diff, largely 
because of some re-indentation.

drm, watchdog, hwmon, i2c, infiniband, input layer, md, dvb, v4l, network,
pci, pcmcia, scsi, usb and sound driver updates. People may appreciate
that the most common wireless network drivers got merged - centrino
support is now in the standard kernel.

On the filesystem level, FUSE got merged, and ntfs and xfs got updated. In 
the core VFS layer, the "struct files" thing is now handled with RCU and 
has less expensive locking.

And networking changes.

In other words, a lot of stuff all over the place. Be nice now, and follow 
the rules: put away the new toys, and instead work on making sure the 
stuff that got merged is all solid. Ok?

Anybody with git can do the shortlog with

	git-rev-list --no-merges --pretty=short v2.6.14-rc1 ^v2.6.13 |
		git-shortlog | less -S

which is actually pretty informative.

2.6.14-rc1 on ATI hangs when executing _STA and _INI methods

My Compaq Presario R3057EA hangs during ACPI initialization. The last
message is "Executing all Device _STA and _INI methods". git bisect
told me that:

    [PATCH] x86-64: i386/x86-64: Fix time going twice as fast problem on ATI Xpress chipsets

    Original patch from Bertro Simul

    This is probably still not quite correct, but seems to be
    the best solution so far.

    Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Passing enable_timer_pin_1 as a kernel boot parameter doesn't help,
but this patch does:

diff --git a/arch/i386/kernel/io_apic.c b/arch/i386/kernel/io_apic.c
--- a/arch/i386/kernel/io_apic.c
+++ b/arch/i386/kernel/io_apic.c

-			if (disable_timer_pin_1 > 0)
-				clear_IO_APIC_pin(0, pin1);
 			return;
 		}
 		clear_IO_APIC_pin(0, pin1);

But doing that is equivalent to reverting the whole patch, so it's
probably not the right solution. My computer has an Intel P4 CPU, ie
it's not x86_64.

Ok. That patch has been one big pain, and was clearly totally half-baked.  
I think I'll disable the automated checks, since they are clearly wrong.
You can still enable it manually with a kernel command line.

So something like this.. I assume this works for you?
