[Bug 1938588] Re: intel-microcode not included 20.04 initrd
Yeah, I knew I'd need to rebuild the initrd to include the microcode vs just including it in the ISO. It would be really nice if Ubuntu's non- live ISOs included the microcode in initrd like the Live ISOs do though. I'm trying to get a hold of someone from the manufacturer and see if they can update their firmware to address the problem, but no luck so far, unfortunately. In the meantime I'll give FreeDOS a shot and see if that works. I already know that doing a full Ubuntu Desktop installation fixes it too, but that obviously takes a long time. If FreeDOS works we can probably use that as a work-around for now until (hopefully) the manufacturer addresses their board problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938588 Title: intel-microcode not included 20.04 initrd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1938588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1938588] Re: Ubuntu Server 18.04.5 install fails: TSC_DEADLINE disabled due to errata
That's disappointing, but understandable. Is there any chance you could provide me with a link to a guide to explain how I could edit the ISO on my own to make a custom ISO for these boards? I've already got some customized preseed files anyway, so making further modifications to the base Ubuntu Server image isn't a big deal. I just don't know what the exact process for adding the microcode would be. My previous efforts using the example script from https://www.kernel.org/doc/html/latest/x86/microcode.html to add the microcode to initrd weren't successful. But I'm not even sure if that's the correct process, or if there's an easier/better way to do it.

[Bug 1938588] Re: Ubuntu Server 18.04.5 install fails: TSC_DEADLINE disabled due to errata
Are there plans to modify the server ISO for 18.04 and 20.04 to address this limitation? Or will I need to modify the initrd file myself and create a customized image for these boards? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938588 Title: Ubuntu Server 18.04.5 install fails: TSC_DEADLINE disabled due to errata To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/1938588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If I boot off the ISO in a VM and use alt+Left I can get to a terminal. `uname -a` reports: ``` Linux (none) 4.15.0-112-generic #113-Ubuntu SMP Thu Jul 9 23:41:39 UTC 2020 x86_64 GNU/Linux ``` I couldn't find that specific kernel package with the search tool, so please feel free to change the package as necessary to something more specific than just "linux" ** Package changed: ubuntu => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938588 Title: Ubuntu Server 18.04.5 install fails: TSC_DEADLINE disabled due to errata To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1938588] [NEW] Ubuntu Server 18.04.5 install fails: TSC_DEADLINE disabled due to errata
Public bug reported: We have several factory-fresh Mitac industrial motherboards (https://www.mitacmct.com/IndustrialMotherboard_PH13FEI_PH13FEI) that we are unable to install Ubuntu Server 18.04.5 on. When we boot from the installation media we get the following error and the installation hangs (see attached screenshot, I've transcribed the error below too) ``` [0.00] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later) [0.157025] ACPI Exception: AE_BAD_PARAMETER, Could not install PciConfig handler for Root Bridge PCI0 (20170831/evrgnini-241) ``` Googling the microcode bug, the normal advice appears to be "boot into an older, functioning kernel, update the `intel-microcode` package, and then reboot." But in this situation there is no older kernel to boot into; there is no OS installed _at all_ on these boards yet. I'm booting from a USB drive loaded with the latest version of Ubuntu Server 18.04. The only work-around I've found that works so far is to install Ubuntu Desktop 18.04, which can boot successfully on these boards, perform the minimal desktop installation, then use the desktop install to update the `intel-microcode` package, reboot, and then finally install Ubuntu Server. This is obviously not convenient needing to install a complete desktop OS just so I can update the microcode, and then immediately wiping it to install what I wanted in the first place. I have not tried Ubuntu 20.x or 21.x; I need to use Ubuntu 18.04 because these motherboards are being installed into robots that will be running ROS Melodic (ROS Noetic runs on 20.04, but these robots don't have Noetic support yet). I have tried the following to modify the Ubuntu Server ISO, without success: 1- Adding the microcode to initrd --- I unpacked the contents of the Ubuntu Server ISO, decompressed install/initrd.gz, and used the bash script here https://www.kernel.org/doc/html/latest/x86/microcode.html to add the intel-microcode firmware to the image. Then I recompressed initrd.gz, and rebuild the ISO using xorisso. This did not have any effect: Ubuntu Server still encountered the same error when trying to install. 2- Using initrd from Ubuntu Desktop 18.04.5 -- I downloaded & unpacked Ubuntu Desktop 18.04.5 and replaced Ubuntu Server's install/initrd.gz with Ubuntu Desktop's casper/initrd (updating txt.cfg and grub.cfg to load the uncompressed initrd instead of the .gz that Ubuntu Server normally uses). Then I rebuilt the Ubuntu Server with xorisso again. The resulted in the system booting, but immediately dropping into an initramfs busybox shell, saying boot files were missing. I assume this is because Ubuntu Server uses the `boot=casper` flag in order to boot into the live desktop session. At this point I'm running out of ideas for how to be able to make Ubuntu Server's installation media work with these boards. Ubuntu Desktop has no problem booting on them, so it's obviously something specific to the Ubuntu Server image, but I'm not sure exactly what or how to fix it. If you need any additional information/logs/etc... please let me know and I'll be happy to provide them.
