Public bug reported: Upon upgrading to grub 2.02-2ubuntu8.10 from 2.02-2ubuntu8.9 all of my machines with /boot/grub on ZFS display a long list of the following sort at boot, before reaching the GRUB menu.
Handle 0x49cb9b98 /ACPI (a0341d0,0)/PCI (0,14)/USB(9.1)/EndEntire USB I/O device path Handle 0x49cb1a1B loaded image Handle 0x4a280e98 d088a413-0a70-4217-ba55-9a3ch64c41b3 This goes on for thousands of lines. On some machines this only takes a few seconds but on other machines this takes over 5 minutes before the GRUB menu is displayed. This is not displayed nor is boot delayed when using grub 2.02-2ubuntu8.9. Secure boot has no effect on the result. Machines with /boot/grub on ext4 do not exhibit this behavior.
