Hi Rob, thanks for your report and sorry for the belated response.
The messages are harmless and don't indicate any actual issue with your board:
@Rob said:
[ 1.506769] Failed to find cpu0 device nodeThis is printed because the ubilinux kernel enables CONFIG_OF and yet the board provides hardware information through ACPI instead of DeviceTree.
[ 2.750257] i801_smbus 0000:00:1f.1: Failed to allocate irq -2147483648: -107
This message was always printed on Apollo Lake systems. This was only fixed recently - see https://patchwork.ozlabs.org/patch/840384/
Thanks!
