Can I get from this test run stdio to the more detailed task, qemurunner or qemu boot logs somehow?
Or do you have to dig into the system manually to capture them, like in the example below?

I would like to check into the detailed logs from both passing and failing test runs.
Of course kernel dmesg would need to be there so maybe after your patch to the runqemu
side at least.

If there is a regression in kernel to the serial device detection and numbering,
then we need some way to see e.g. 8250 uart/tty0/ttyAMA0 related dmesg messages.

Cheers,
