[Bug 1904054] Re: kernel 5.8 general protection fault at boot
Just tried the newly released 5.8.0-31-generic, but I'm still seeing the GPFs (see attached screenshot). I'm continuing to run with the mainline 5.9.10 kernel that I mentioned previously, not ideal since I had to switch to the upstream openzfs-2.0 release which supports the 5.9 kernel. ** Attachment added: "PXL_20201201_233259297.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+attachment/5440157/+files/PXL_20201201_233259297.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904054 Title: kernel 5.8 general protection fault at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1904054] Re: kernel 5.8 general protection fault at boot
OK, after a lot of kernel package installs and rebooting... Mainline kernel version 5.8.5-050805 boots and runs successfully. But the *next* version (5.8.6-050806) generally fails to boot, exhibiting the pattern of GPFs and occasional kernel panics. Once it booted up all the way, but the system hung shortly after booting up. Ubuntu kernel version 5.4.0.52-generic continues to be very reliable on this system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904054 Title: kernel 5.8 general protection fault at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Mainline kernel version 5.8.0-050800-generic boots up without any issues. Mainline kernel version *5.8.18-050818-generic* doesn't (GPF and kernel panics). I'll work backwards from 5.8.18-050818-generic to see when the GPFs and kernel panics go away. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904054 Title: kernel 5.8 general protection fault at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1904054] Re: kernel 5.8 general protection fault at boot
It maybe worth checking with one or more of the mainline kernels to see if these behave differently from the Ubuntu kernel just to see if they boot fine or if they suffer from the same issue. The mainline kernels can be found in https://kernel.ubuntu.com/~kernel- ppa/mainline For example, it may be worth installing the initial 5.8 kernel release https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/ - use the following: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-headers-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-headers-5.8.0-050800_5.8.0-050800.202008022230_all.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-image-unsigned-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-modules-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb If this boots OK, then maybe then try the latest mainline 5.8 kernel in https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8.18/ Failing that, it may be worth trying the mainline kernels from 5.5..to 5.7 too to see when the issue starts to occur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904054 Title: kernel 5.8 general protection fault at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1904054] Re: kernel 5.8 general protection fault at boot
I may be useful to add "debug ignore_loglevel" to the kernel boot command line to get more debugging information during boot to see which module is tripping this issue. edit the /etc/default/grub (as the root user) and add the debug and ignore_loglevel keywords to the GRUB_CMDLINE_LINUX_DEFAULT GRUB_CMDLINE_LINUX_DEFAULT="quiet splash debug ignore_loglevel" then run: sudo update-grub and reboot.

[Bug 1904054] Re: kernel 5.8 general protection fault at boot
Ah, according to the openzfs release notes, openzfs version 0.8.4 (the current version in the ubuntu repositories) isn't compatible with kernel versions later than 5.6. Presumably this is the issue. I guess I'll stick with kernel 5.4.x until update ZFS packages are released. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904054 Title: kernel 5.8 general protection fault at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1904054] Re: kernel 5.8 general protection fault at boot
I was able to successfully boot with upstream kernel version: 5.10.0-051000rc3-generic This kernel package notably does not include the ZFS kernel modules (and those kernel modules did not build when I installed zfs-dkms). So it does seem possible that the bug I'm encountering relates to ubuntu kernel 5.8 and the various ZFS related kernel modules. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904054 Title: kernel 5.8 general protection fault at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
