Title:
4.8.0-16.17: genirq: Flags mismatch serial vs goldfish_pdev_bus
Status in cloud-images:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Yakkety:

Bug description:
I usually run kvm with '-serial stdio' after adding
GRUB_CMDLINE_LINUX_DEFAULT="console=ttyS0" to /etc/default/grub. This
will give me a serial console where I can login and, more important,
get kernel logs.
After install 4.8.0-16.17 I'm unable to login in the serial console,
and I'm getting a lot of messages:
genirq: Flags mismatch irq 4. 00000000 (serial) vs. 00000080
(goldfish_pdev_bus)
System seems to be working fine otherwise.
4.8.0-15.16 didn't show this behaviour.
The obvious suspect commits are the "SAUCE: irqchip/gicv3-its:*" in
-16, although the several config changes may also be involved.
