[Bug 1093217] Re: 8086:0166 [Lenovo IdeaPad Z580] 12.04-13.10 10-20min boot delay (From 3.2.0.29-3.12-rc2)
The only way I have been able to get the patched DSDT to work is to build it into the kernel. This is less than ideal but will allow you to use your computer. If you have been unable to get a patched DSDT to work, this should work for you. I am currently running 14.04 with a custom kernel build. The following should work with other kernel versions as well. I am only posting the steps exactly as I performed them, so if version number etc don't match for you, you are on your own. 1) Install Ubuntu 14.04. If you have to, just pull out your battery and complete the installation. Just leave it out until we are finished. 2) Compile your custom DSDT - this should produce a DSDT.hex file that you will need for incorporation into the kernel. sudo iasl -tc DSDT.dsl 3) Get the source: sudo apt-get source linux-image-3.13.0-24-generic 4) Untar the source: gzip -cd linux_3.13.0.orig.tar.gz | tar xvf - 5) Move into the directory that contains the kernel source code and apply the patch: cd linux-3.13/ gzip -cd ~/linux_3.13.0-24.47.diff.gz | patch -p1 6) Get the required tools to build the kernel sudo apt-get install git-core libncurses5 libncurses5-dev libelf-dev asciidoc binutils-dev linux-source qt3-dev-tools libqt3-mt-dev libncurses5 libncurses5-dev fakeroot build-essential crash kexec-tools makedumpfile kernel-wedge kernel-package gcc 7) Configure the kernel for compilation: make menuconfig When the menu comes up navigate to Power Management and ACPI options - ACPI In the field Custom DSDT Table file to include enter the path to your DSDT.hex file which for me was /home/DSDT.hex Now navigate to General Setup (you will have to go back to the main menu) In the field Local Version enter -custom-dsdt Now navigate to Device Drivers - Generic Driver Options Deselect the field Prevent Firmware from being built Select save at the bottom, accept the default file name and exit 8) Build the kernel: sudo make -j3 deb-pkg At this point, just walk away from you computer. Come back every so often to check on the progress but the build will probably take a couple of hours(depending on your system). Try to resolve it and retry building the kernel 9) Install the kernel: sudo dpkg -i linux-image-3.13.9-custom-dsdt_3.13.9-custom-dsdt-4_amd64.deb This will install the new kernel. If it completes successfully, reboot your system. The default grub option should now be your new kernel. You can verify the custom DSDT is loaded in dmesg and you should see your custom version number with the uname -r command. If all goes well power off your computer, reinstall your battery, and boot your computer up. Let me know if I missed anything and good luck. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1093217 Title: 8086:0166 [Lenovo IdeaPad Z580] 12.04-13.10 10-20min boot delay (From 3.2.0.29-3.12-rc2) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1093217/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think that I have found the culprit code change that is causing the
slow boot issue. I have been comparing changes across the 3.2, 3.5, and
3.8 kernels and paying attention to the changes that remained the same
across the 3.5 and 3.8 sources.
All calls to exit_idle() and irq_enter() were reversed from the 3.2 kernel to
the 3.5 and 3.8 kernels in the file arch/x86/kernel/apic/apic.c. I reversed
them all to match the 3.2 kernel and have been booting successfully with this
kernel build. I have tried booting in every combination I could think of
(quickly and slowly booting from grub, booting plugged in and uplugged etc.).
My changes are marked by the ADDED and REMOVED comments. The following is a
copy of all the functions I edited.
void __irq_entry smp_apic_timer_interrupt(struct pt_regs *regs)
{
struct pt_regs *old_regs = set_irq_regs(regs);

i++;
v1 = 1;
}
apic_printk(APIC_DEBUG, KERN_CONT \n);
irq_exit();
}
Other than the changes at the ADDED and REMOVED comments the source code
I used to build my kernel is identical to 3.8.0-23.34, which I believe
is the latest Raring kernel.
I am not sure how to submit these changes for approval/testing, is
anyone willing to apply these changes and test it out on their machine
and/or submit the changes?

I realized I built the kernel with ACPI debugging enabled, rebuilt the kernel and now it doesn't work.

I am not sure if it fixed my computer or not. I seem to have better luck booting than a lot of people for some reason. Because the issue has occurred after a kernel update, I am just suggesting that maybe altering the DSDT is not the best solution to this problem(especially since Windows 8 is using the same code and it boots 100% of the time). I did compile a kernel with the altered DSDT and it does seem to boot without problems. I have also tried diffing the 3.2 and 3.8 kernels and backing out some changes, focusing on the battery.c code in the ACPI drivers, but I have not been able to find anything that affects boot time. Anyone have any ideas on where else to look? You should try booting your computer with some of the OS options that are listed in your decompiled DSDT. Until a solution is found, altering the DSDT is a good temporary solution(in my opinion). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1093217 Title: Ubuntu 12.04/12.10/13.04 10-20min boot delay (From 3.2.0.29-3.8.0.19) [Lenovo IdeaPad Z580] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1093217/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I found that there is also a Linux option you can try too. It looks like there is a list of OS names in the DSDT and if Ubuntu isn't supplying one of those names, a lot of things don't get initialized properly. After saying that the Windows 2012 option was working, it immediately stopped workingSo I am using the LInux option now and it seems to be working.

After a lot of digging, I found that the DSDT for my Windows 8 and Ubuntu are nearly identical. There is no delay in the WAEC method that Windows 8 is using. In method _OSC of the decompiled DSDT, there is a test against the OS name reported to the ACPI. In my case, I am dual booting with Windows 8 and the name that is being checked for is Windows 2012. That being said, I looked into my dmesg and the acpi command was not working for me either, just extra magic in my computer I guess :). Remove the acpi command from the grub.cfg menu entry for the version of Ubuntu you are running add the kernel parameter acpi_os_name=Windows 2012 as follows: linux /boot/vmlinuz-3.8.0-19-generic root=UUID=b6449636-2d59-426d- 88e4-4f6132af9e2f ro crashkernel=384M-2G:64M,2G-:128M quiet splash $vt_handoff acpi_os_name=Windows 2012 If you are not running Windows 8, you may have to put a different string in for the acpi_os_name. My magic ran out when I upgraded to 13.04. I have been using this to boot 13.04 with no issues.

I am always booting in UEFI mode. I put the patched DSDT in the same location, but I edited /boot/grub/grub.cfg to include acpi /boot/DSDT.aml just before the linux and initrd load commands. This works for me on every boot.
