We now also have: https://autobuilder.yoctoproject.org/typhoon/#/builders/60/builds/2460 which is hanging in a dnf command. >From the autobuilder, I couldn't ssh into the image, it hangs but 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. Cheers, Richard
