[Bug 1904243] Re: 21.04 Panics attempting to boot 5.10.0-3.4 in gcp EFI disk
This is likely the same underlying root cause as https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1901633. The system is failing to fallback to the initrd path and therefore gets stuck in a reboot/panic loop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904243 Title: 21.04 Panics attempting to boot 5.10.0-3.4 in gcp EFI disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904243/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I was not able to reproduce this: ubuntu@fginther-hirsute:~$ lsb_release -c Codename: hirsute ubuntu@fginther-hirsute:~$ uname -a Linux fginther-hirsute 5.10.0-4-generic #5-Ubuntu SMP Mon Nov 16 09:45:27 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux ubuntu@fginther-hirsute:~$ cat /etc/cloud/build.info build_name: minimal serial: 20201114 I booted a minimal hirsute image by mistake, but it should be close. Also, the kernel was up to 5.10.0-4 when I tested. There could still be some compatibility issue in play here. Let's see how the next round of testing goes. ** Changed in: linux (Ubuntu Hirsute) Assignee: (unassigned) => Francis Ginther (fginther) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904243 Title: 21.04 Panics attempting to boot 5.10.0-3.4 in gcp EFI disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904243/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
