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. ** Affects: linux-azure (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752999 Title: [Hyper-v] Set CONFIG_I2C_PIIX4 to "n" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1752999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
