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.
