Sometimes there is simply no serial connection available - you are travelling and using Turmvilla/Heeselicht or simply there is no UART in your machine.

To get nevertheless the messages from core or the kernel it would be nice if they are exported as ordinary Genode ROM in order to inspect them if required.

This feature is not meant for very early trouble solving. You will need to have already your system running up to some degree so that you can save the output somewhere (RAM) and additionally have some way of exporting the output - wifi/nic/ahci/sd/usb etc.

Nice to see that this topic is still alive though we discussed last in May 2016. I'll have a look at it over the next week.

Would GRUB's usb_serial driver be useful?
