Bug Description
Issue found on Jammy 5.15.0-36.37 ARM64k with AWS instance a1.medium (passed with ARM64 a1.medium)
This is not a regression, as this issue can be found since 5.15.0-28.29
The reason is that the lttng module will failed to build on this instance:
$ time sudo apt install lttng-modules-dkms

At the very beginning I thought it's because the ram is too small on this instance:
$ free -h
Mem: 1.8Gi 425Mi 1.0Gi 15Mi 347Mi 1.1Gi
Swap: 0B 0B 0B
But if you install the generic arm64 kernel on this node and remove the generic-64k one, the module can be built in about 14 minutes (for the generic and aws kernel, with just the generic kernel it will be just 7 minutes)

I tried to bump the timeout from 20 minutes to 40 minutes, but it's still failing.
Looks like it's been killed by the system:
