With this patch in the tree, I get some interesting crashes in Seabios
if I provide a somewhat unusual command line option. For example,
something like
-usb -device usb-ehci,id=ehci \
-device usb-uas,bus=ehci.0,id=uas \
-device scsi-hd,bus=uas.0,scsi-id=0,lun=0,drive=d0 \
-drive file= ...
is accepted as command line option but results in

SeaBIOS wants SYSTEM HALT.
This is without --nodefaults, and it used to work. Is that intentional ?
If I do use the --nodefaults parameter, I was unable to figure out how
to configure the serial console. What command line parameter(s) do I need to
get it ?
Thanks,
