I chose the default UFS selection in the iso installer. > Happy to change it to something better. you're starting your bhyve with a -s that specifies the ahci-hd driver. the guest kernel therefore sees an 'ahcich0' device. if you start bhyve with a -s that specifies the virtio-blk driver, then your guest kernel will see a 'vtblk' device. this may matter, since the kernel timeout you showed was in the ahci driver. i have never used this driver in bhyve. -- P Vixie
