Description Mathieu Dubois-Briand 2026-08-11 14:32:37 UTC 
Happened once on master-next. I don't see any useful log in there :(

QMP released QEMU at 08/09/26 10:21:41 and took 0.11 seconds from connect
WARNING: core-image-ptest-quilt-1.0-r0 do_testimage: Couldn't login into serial console as root using blank password
WARNING: core-image-ptest-quilt-1.0-r0 do_testimage: The output:


qemux86-64 login: <<< run_serial(): command timed out after 120 seconds without output >>>

qemu is up and running but the serial console is in an odd state.
Let's see how often this happens.
