We now also have:

https://autobuilder.yoctoproject.org/typhoon/#/builders/60/builds/2460

which is hanging in a dnf command.

tantalisingly, it would show me the time of the last login. I was
therefore able to run dmesg and confirm there is nothing in the logs
relating to this hang. I can't get a shell (bash or ash), top won't
run. Not sure what else to try but I am pretty sure this is our 512MB
memory bug, its still there. I'll leave it running for now in case
anyone has better ideas about debugging.

Richard
