Hmm, I wasn't seeing anything in the raw log, which doesn't collapse sections..

That said, I still think uart is preferable to ssh for kernel CI.. we
aren't running jobs at the scale of mesa CI jobs so even if we get
UART flakes 1/1000 (or even 1/100) times, that is an acceptable
trade-off for the fact that uart can still work when things are too
fubar for ssh.
