[Bug 1808418] Re: Thinkpad T430u won't boot without noapic workaround
** Description changed: + (For anyone coming to this bug for the first time, the current + workaround is to add this to the kernel boot parameters: intremap=off) + I've used Ubuntu on this specific machine for years without problems, but starting with the 4.13 kernel that came with the 17.10 HWE and continuing into 18.04 kernels my computer would no longer boot, hanging at various screens: - A blank screen with a flashing cursor - A screen with this message: Loading Linux 4.13.0.36-generic ... Loading initial ramdisk ... - A screen with kernel messages, ending in: APCI: EC: interrupt blocked I've encountered the bug in a number of kernels, including: - 4.13.0-32 - 4.13.0-36 - 4.13.0-37 - 4.15.0-24 - 4.15.0-34 - 4.15.0-36 - 4.15.0-38 - 4.15.0-42 - 4.20.0-rc7 I was able to work around the issue by adding noapic to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default grub, e.g.: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic" I'm not entirely sure of the consequences of this workaround, but one thing I've noticed is significantly reduced battery life.

[Bug 1808418] Re: Thinkpad T430u won't boot without noapic workaround
I've done some more testing and built tags v5.7 and v5.7-rc2 from source. v5.7-rc2 seems to consistently boot without any special kernel flags v5.7 gives me rather odd behaviour: - When I'm first powering on the machine, v5.7 does not boot without any special kernel flags - If I set intremap=off, it will boot every time, but not if I remove it - If I boot v5.7 once with noapic, it will boot, then it will continue to boot after I remove it, but only if I restart. If I power off, it will not boot So I would consider v5.7 to be affected by this bug, and I'll do a rebase between the v5.7-rc2 and v5.7 tags. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808418 Title: Thinkpad T430u won't boot without noapic workaround To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808418/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Very odd... 5.7 boots (without noapic or intremap=off), but not consistently.

Most of the time after powering off/powering back on it boots fine again, without needing to modify the kernel parameters.

[Bug 1808418] Re: Thinkpad T430u won't boot without noapic workaround
I'm hopeful that doing the bisect over again will find a more relevant commit. While bisecting this time I ran into a weird scenario the I believe may have affected the previous attempts to do a bisect. The short version of this is that when the computer has failed to boot a kernel (without noapic), all kernels seem to fail until I've successfully booted once with noapic. I have a feeling this has hampered many of my troubleshooting efforts. For a more detailed idea of what this looks like, this is what happened when I realized the problem: 1. I compiled, installed, and booted to 4.12.0-rc2 2. I rebooted and it worked, so I marked it as good and then powered off the computer 3. Later I powered on to resume the bisect but I wasn't paying attention at the Grub menu and accidentally booted 5.3 (without noapic), which failed 4. I then tried to boot 4.12.0-rc2 without noapic, and it wouldn't boot 5. I booted with 4.12.0-rc2 with noapic, and then rebooted and booted 4.12.0-rc2 without noapic, and once again it booted successfully -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808418 Title: Thinkpad T430u won't boot without noapic workaround To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808418/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I haven't reformatted my machine in years and was running into some other issues, so I just did a reinstall of 18.04. With both the install media and the latest 18.04 kernel (4.15.something), I needed noapic. So I installed kernel v4.20.4-042004, and it would not boot without noapic either. However, after I boot to v4.20 with noapic one time, I can remove it and it seems to boot fine. So the issue persists with the latest kernels albeit slightly differently. When I get a chance I'll try to figure out which kernel the problem started since apparently the problem hasn't yet been resolved.

I'm assuming I should add apic=debug to a kernel that has the bug (and not one that boots fine), correct?

Maybe you can try adding 'apic=debug' and remove 'quiet splash' parameters when you boot and see if kernel shows more messages that can point to the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808418 Title: Thinkpad T430u won't boot without noapic workaround To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808418/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I tried to boot with an older kernel (4.15.0-43), and it wouldn't boot without noapic. But v4.20-rc7 seems to boot fine. I guess it must've been a fluke that it didn't boot for me the first time.

[Bug 1808418] Re: Thinkpad T430u won't boot without noapic workaround
I'm still using v4.20-rc7, and I wanted to try some more kernel parameters to narrow down the problem. Since the last kernel messages I got using earlyprintk (https://gist.githubusercontent.com/bmaupin/b743bb3325e100341c62ee62e713d8a4/raw/7372dddb5704d3f15ff429807355d5d3686165d2/boot7.png) were related to the Spectre mitigations, I removed noapic and replaced it with spec_store_bypass_disable=off and it booted. Oddly enough then I removed spec_store_bypass_disable=off altogether and it booted without any special parameters. So I don't fully understand what happened, but it seems like my system boots fine now without any special parameters. I'll remove v4.20-rc next and see if it still boots with the kernels from Bionic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808418 Title: Thinkpad T430u won't boot without noapic workaround To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808418/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Loading initial ramdisk ... - A screen with kernel messages, ending in: APCI: EC: interrupt blocked I've encountered the bug in a number of kernels, including: - 4.13.0-32 - 4.13.0-36 - 4.13.0-37 - 4.15.0-24 - 4.15.0-34 - 4.15.0-36 - 4.15.0-38 I was able to work around the issue by adding noapic to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default grub, e.g.: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic" I'm not entirely sure of the consequences of this workaround, but one thing I've noticed is significantly reduced battery life. + This bug seems very similar to what's described here for the Thinkpad + E485/E585: + https://web.archive.org/web/20180919160303/https://evilazrael.de/content + /getting-linux-boot-lenovo-thinkpad-e485e585 + I'll attach screenshots of various times I've encountered this bug over the last year. + + $ lsb_release -rd + Description: Ubuntu 18.04.1 LTS + Release: 18.04 + + $ apt-cache policy linux-image-4.15.0-42-generic + linux-image-4.15.0-42-generic: + Installed: 4.15.0-42.45 + Candidate: 4.15.0-42.45 + Version table: + *** 4.15.0-42.45 500 + 500 http://us.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages + 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages + 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-42-generic 4.15.0-42.45 ProcVersionSignature: Ubuntu 4.15.0-42.45-generic 4.15.18 Uname: Linux 4.15.0-42-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: - USERPID ACCESS COMMAND - /dev/snd/controlC0: bryan 2349 F pulseaudio + USERPID ACCESS COMMAND + /dev/snd/controlC0: bryan 2349 F pulseaudio CurrentDesktop: XFCE Date: Thu Dec 13 15:31:15 2018 HibernationDevice: RESUME=UUID=4afa8032-cfe5-45f4-a626-738ab33904ac InstallationDate: Installed on 2014-05-08 (1680 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: LENOVO 3351CTO ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-42-generic root=UUID=cffbc87d-956b-4986-94df-b3b64ae5237f ro quiet splash noapic vt.handoff=1 RelatedPackageVersions: - linux-restricted-modules-4.15.0-42-generic N/A - linux-backports-modules-4.15.0-42-generic N/A - linux-firmware 1.173.2 + linux-restricted-modules-4.15.0-42-generic N/A + linux-backports-modules-4.15.0-42-generic N/A + linux-firmware 1.173.2 SourcePackage: linux UpgradeStatus: Upgraded to bionic on 2018-07-12 (154 days ago) dmi.bios.date: 06/01/2018 dmi.bios.vendor: LENOVO dmi.bios.version: H6ETA0WW (2.18 ) dmi.board.asset.tag: Not Available dmi.board.name: 3351CTO dmi.board.vendor: LENOVO dmi.board.version: Win8 STD DPK TPG dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrH6ETA0WW(2.18):bd06/01/2018:svnLENOVO:pn3351CTO:pvrThinkPadT430u:rvnLENOVO:rn3351CTO:rvrWin8STDDPKTPG:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.family: ThinkPad T430u dmi.product.name: 3351CTO dmi.product.version: ThinkPad T430u dmi.sys.vendor: LENOVO -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808418 Title: Thinkpad T430u won't boot without noapic workaround To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808418/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
