Public bug reported:
Affects: Trusty, Xenial, Bionic linux-azure
Hyper-V Generation 1 virtual machines have a PIIX4 device because that's
where the IDE controllers are, but when CONFIG_I2C_PIIX4 is enabled,
users will see the following error in the boot log:
[ 5.139414] piix4_smbus 0000:00:07.3: SMBus base address
uninitialized - upgrade BIOS or use force_addr=0xaddr
Potentially this slows down the boot as well.
Please set CONFIG_I2C_PIIX4 to "n" in linux-azure builds.
