Is there specific information you'd like from the VM? I just recreated the problem and can extract. The last image that succeeded getting built is publically available, so you could create a gcp VM for that, go to /usr/src/linux, git pull, make & install the new kernel and reproduce the problem that way. The git pull will take a bit because it's a shallow clone... gcloud compute instances create myvm --preemptible --project your-gcp-project --image-project pg-ci-images --image pg-ci-sid-newkernel-2022-08-12t06-52 --zone us-west1-a --custom-cpu=4 --custom-memory=4 --metadata=serial-port-enable=true If you want to log in via serial console, you'd have set a password before rebooting. gcloud compute connect-to-serial-port --zone us-west1-a --project=pg-ci-images-dev myvm Executing the script requires a gcp key with the right to create instances and images. Here's how to invoke it: PACKER_LOG=1 GOOGLE_APPLICATION_CREDENTIALS=~/image-builder@pg-ci-images-dev.iam.gserviceaccount.com.json \ packer build \ -var gcp_project=pg-ci-images-dev \ -var "image_date=$(date --utc +'%Y-%m-%dt%H-%M')" \ -var "task_name=sid-newkernel" \ -only 'linux.googlecompute.sid-newkernel' \ -on-error=ask \ packer/linux_debian.pkr.hcl Of course you'd need to change the gcp_project= variable to point to a the project you have access to and GOOGLE_APPLICATION_CREDENTIALS to point to your gcp key. Initially (package upgrades, kernel builds) the VM would be SSH accessible. After building the kernel it's only accessible via serial console. I can probably also get you the image in some other form that you prefer, although I don't know if the problem will reproduce outside gcp. If helpful I could upload a "broken" gcp image that you could use to > > [1] https://github.com/anarazel/pg-vm-images/blob/main/packer/linux_debian.pkr.hcl#L225 Greetings, Andres Freund

Actually, after reproducing I seem to now hit a likely different issue.

Tsirkin <mst@redhat.com> I'm not 100% confident yet, because the likelihood of encountering problems was not uniform across the versions, with one of them showing the problem only in 1/3 boots, whereas some of the others showed it 100% of the time. But I've rebooted enough times to be fairly confident. With 762faee5a267 I reliably see network not connecting, with 762faee5a267^=fe3dc04e31aa I haven't seen a problem yet. I did see some other types of crashes in commits nearby, so this might not be the only problematic bit.
