dmesg after booting without noapic an dnolapic

Boots very slowly without noapic and nolapic, presumably from some sort of bug with ACPI/Bios/Firmware... I have tried this with both mainline and the Archlinux default kernel, both of which have the same issues, though the Arch kernel boots a little more quickly without noapic/noalpic.

Lots of these bugs:
[Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored

I fear this is affecting performance, as without apic and lapic dynticks don't work correctly, to my knowledge.

Attached is a dmesg from booting without noapic and nolapic, a dmesg with noapic nolapic, as well as the output of lspci and lsusb.

After some more digging it seems this is also related to EFI/UEFI. I am unable to load uefivars, as modprobe reports the device doesn't exist on this system, leading me to believe whatever firmware it uses hasn't had support yet been built into the kernel...it'd be nice to have that so I can use grub2 with EFI for faster booting.

> [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored

please attach the output from acpidump so we can verify
that you can ignore those.

re: speed issue

please try booting with "intel_idle.max_cstate=0"

acpidump

The speed issue is gone as of ... .38 or so. There are still firmware issues and I've even forced OSI as Linux, which makes the bugs say they're using Linux instead of the default Windows emulation thing...

Either way, I recently fixed my DSDT and tried it, and that ended up actually making my plugged in status and some other ACPI functions break. Attached is the acpidump. I'll add the original and fixed versions of the dsdt files below too.

FYI, the repeated OSI(Linux) warning has been reduced to one,
as of this patch in Linux 3.1 merge window:


commit 8997621bb2daaf19a4e9d82f118224159d8054e2
Author: Len Brown <len.brown@intel.com>
Date:   Tue Aug 2 00:45:48 2011 -0400

    ACPI print OSI(Linux) warning only once
    
    This message gets repeated on some machines:

So you at least took the annoying factor back down to 1 from something like 50...that's pretty nice.

I guess I still need to figure out the best way to fix my DSDT? It compiles without errors or warnings with the fixes I found, it's just as I said it tends to break some things...
Comment 11 Matt Parnell 2011-08-06 20:02:11 UTC
I merged in your acpi fixes with my local repo (a clone of git.zen-kernel.org/zen-stable/ ) and it merged in well, but I still get repeated firmware errors...it's a 2.6 kernel, but I'd have expected it to work there too.

I'll try 3.1 when I get a chance, with your patch.

It's great that the kernel bugzilla is back.

Can you please verify if the problem still exists in the latest upstream kernel?
Comment 13 Zhang Rui 2012-05-24 07:53:03 UTC
bug closed as there is no response from the bug reporter.
please feel free to reopen it if the problem still exists in the latest upstream kernel.
