Maybe related to Bug 208308. When mounting USB drive from fstab and the sixth field, (fs_passno), is set to 2 the boot sequence hangs. Setting fs_passno to 0 work as expected. Tested with different types of drives (memstick and disk) with different schemes (MBR, GPT) and all combination of msdosfs and/or ufs. Adding 'late' to fstab have no effect. (fsck comes before mount) Steps to reproduce (memstick): /etc/fstab: /dev/da0s1 /mnt msdosfs rw,noatime 0 0 This work OK. /etc/fstab: /dev/da0s1 /mnt msdosfs rw,noatime 0 2 This should start a background fsck and the boot would proceed as normal. Tested on RaspberryPi3: Booting hangs after enumerating all USB devices. You have to remove SDHC-card and mount it on another machine and edit /etc/fstab. Eventually after fsck of SDHC.

(In reply to pru13allan from comment #0) Adding USB drives after boot and ending up with FreeBSD hung up is one part of bugzilla 224330 . This is tied to head -r326347 in some way, although -r327347 may have just exposed a problem elsewhere. The original context was Pine64+ 2GB's. If you do not mount the USB drive at all via /etc/fstab, and, do not plug it in until after FreeBSD has booted, do you still get a hangup when the drive is plugged in? If not, can you then mount it manually? Such questions are mostly tied to getting an initial clue how independent the bugzilla reports are.
The problem with the hang is only related to when I want to have the USB-disk checked at boot (/etc/fstab -> fs_passno = 2). If I set fs_passno = 0 it works without any problems. It gets mounted automatcally with the info from /etc/fstab. I don't get the filesystem checked before mounting though.
