Hello, since 5.4.0-92 we're also experiencing this issue on Ubuntu 20.04.3 VMs on two Hyper-V 2012r2 servers. On the same servers there are also other VMs with this kernel (and 5.4.0-94) booting without issues. As described earlier, booting some times works, sometimes doesn't.
Setting `debug=all` for GRUB and adding `boot_delay=5000 panic=0` to the kernel params reveals that after `loader/efi/linux.c:96: kernel_addr: 0x2bfa1000 handover_offset: 0x190 params: 0x3ec0f000` the system just reboots. I have, however, not found the event that @lucas-navarezi mentioned in the Hyper-V-Worker log. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1918265 Title: Random boot failure with Ubuntu 20.04 / grub 2.04 and Hyper-V 2012r2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1918265/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
