description |
Ubuntu Focal (and new releases) on AWS will normally boot without an initrd image (just the microcode.cpio). There is a fallback mechanism to reboot with the full initrd image when the boot fails to complete. The grub environment variable "initrdfail" is used to track when a boot failed and switch between the optimized initrd-less boot path and the full initrd path.
On a normal successful boot, the "initrdfail" variable is cleared by grub-initrd-fallback.service. However, this doesn't happen when resuming from hibernation. As a result, the initrd fallback will get triggered on the second hibernation / resume cycle despite the original boot using only the microcode.cpio. This switch in initrd images leads to the second resume hanging.
We've been able to successfully avoid this issue by adding the following to the ec2-hibinit-agent resume handler:
/usr/bin/grub-editenv - unset initrdfail
/usr/bin/grub-editenv - unset recordfail
(Note: clearing recordfail may not be necessary, will need to try again without it.)
This bug was filed against grub2 as it appears to own initrdfail. |

[Test plan]
TBD w/ CPC
[Regression potential]
Services get changed to oneshot, and wantedby=multi-user sleep; maybe we miss other places it should run, or record the wrong thing on resume? |
