[Kernel-packages] [Bug 1880032] Re: [linux-azure] Enable Hibernation on The 18.04 and 20.04 5.4 Kernels
Detailed steps to repro the issueo on Azure: 1. Create a VM with the image "Ubuntu Server 20.04 LTS - Gen1". Any VM size should be fine. Here I use "Standard E4-2ds_v4 (2 vcpus, 32 GiB memory)". 2. Add an extra disk of 64GB to the VM via Azure portal. 3. Login the VM via ssh and check the kernel version: here I get 5.4.0-1022-azure. 4. In the VM, the 64GB disk can be sdc. Let's create a swap partition in it, i.e. sdc1. 5. mkswap /dev/sdc1 root@decui-tmp-2004:~# mkswap /dev/sdc1 Setting up swapspace version 1, size = 64 GiB (68718424064 bytes) no label, UUID=544831e4-72ab-4d2c-81aa-6dac3a8e20ad 6. Add the swap partition info into /etc/fstab: UUID=544831e4-72ab-4d2c-81aa-6dac3a8e20ad none swap sw 0 0 7. Use "swapon -a; swapon -s" to confirm that the swap partition works. 8. Add the kernel parameter resume= into /etc/default/grub.d/50-cloudimg-settings.cfg: GRUB_CMDLINE_LINUX_DEFAULT="console=tty1 console=ttyS0 earlyprintk=ttyS0 resume=UUID=544831e4-72ab-4d2c-81aa-6dac3a8e20ad ignore_loglevel no_console_suspend" Note: here I also add "ignore_loglevel no_console_suspend", which are *required* to see the error messages during hibernation. 9. Comment out the only line in /etc/default/grub.d/40-force-partuuid.cfg: GRUB_FORCE_PARTUUID=bf00dea3-136e-49cb-a640-0df7ce49d6db Note: this step is required, otherwise the generated grub.cfg doesn't contain the "initrd ..." line , which is required for resuming to work. 10. Run "update-grub2; reboot". Note: this 'reboot' might be a must, because we'll need to re-generate the initramfs when the running kernel has the resume= parameter. 11. Login the VM again and run "update-initramfs -u". 12. Run "echo disk > /sys/power/state". Note: we'd better run this command from Azure serial console (we need to set a password for root and use that to login via the serial console) so we can easily watch what will be happening. root@decui-tmp-2004:~# echo disk > /sys/power/state [ 67.838749] PM: hibernation entry [ 68.266627] Filesystems sync: 0.041 seconds [ 68.271740] Freezing user space processes ...

No other change is needed.

be included.

To reproduce the issue, I created a Ubuntu 20.04 VM on Azure (the kernel version was "5.4.0-1022-azure #22-Ubuntu"), and I ran "echo disk > /sys/power/state" in the VM and then checked the Azure serial console of the VM and found the warning in commen #8 and suspending couldn't finish normally (it looks the VM got a fatal page fault error later).

[Kernel-packages] [Bug 1880032] Re: [linux-azure] Enable Hibernation on The 18.04 and 20.04 5.4 Kernels
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=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

[Kernel-packages] [Bug 1880032] Re: [linux-azure] Enable Hibernation on The 18.04 and 20.04 5.4 Kernels
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.
