There is another important bug fix for hibernation:
net/mlx5: Fix crash upon suspend/resume (https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=8fc3e29be9248048f449793502c15af329f35c6e).

So far the fix is only present in the net.git tree, but I expect it will be in the mainline tree’s v5.8-rc1 (or even v5.7, if we’re lucky).

Please consider picking it up. Thanks!

Unluckily this commit breaks hibernation:
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"

Now I'm seeing a hang/panic issue when hibernating the VM ("5.4.0-1022-azure #22-Ubuntu"):
