I have an AMD "hammer" (9590) running a bhyve with a VM that used to be a "droplet". All is good if I run "vm -f start <droplet>" it works. That is: the console is attached to stdin/stdout of the vm command. If, however, I start without the -f, I get the linux kernel "not" booting with output of: [ 54.548000] serial8250: too much work for irq4 [ 57.412000] serial8250: too much work for irq4 [ 61.040000] [sched_delayed] sched: RT throttling activated [ 61.044000] serial8250: too much work for irq4 [ 63.892000] serial8250: too much work for irq4 [ 66.760000] serial8250: too much work for irq4 [ 69.656000] serial8250: too much work for irq4 ... so suboptimal.
