Bug Description

[Impact]

We backported several upstream commits in LP #1880032, but the following commit wasn't necessary and it's causing a panic when trying to hibernate an azure instance, as described by comment #8 in LP #1880032 (https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1880032/comments/8):

0a14dbaa0736 ("video: hyperv_fb: Fix hibernation for the deferred IO feature"):
https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-azure/+git/focal/commit/?h=Ubuntu-azure-5.4.0-1022.22&id=0a14dbaa0736a6021c02e74d42cf3a7ca5438da6

We should include the patch only if the kernel also includes
a4ddb11d297e ("video: hyperv: hyperv_fb: Support deferred IO for Hyper-V frame buffer driver"

I manage to reproduce the panic and I can confirm that reverting the offending commit solves the problem. I managed to test it on several D and E instances types and the system successfully hibernates. I also tried to test the scenarios where the system has high memory usage and on a 8GB VM hibernation worked up until 70% of memory utilization.

[Test Case]

Follow the steps from https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1880032/comments/14.

[Regression Potential]

The revert touches the Hyper-V framebuffer driver and can potentially cause the VM to not boot or cause hibernation to fail (again). Although the risk is low.
