9.2.1.7 boot hangs for process smartctl

[voj]

After updating from earlier 9.2 (maybe 9.2.1.5) to 9.2.1.7 FreeNAS boot hangs indefinitely running command smartctl (checked with Ctrl-T). On screen the last lines are

Starting devd.
em0: link state changed to UP
lagg0: link state changed to UP
em1: link state changed to UP​

I have left it running for several days (I think 4-5 days at one time) and nothing seemed to happen. So I will always just have someone press Ctrl-C and the boot continues. Pressing Ctrl-C causes a trace to be printed; the first lines of it scroll out of the screen and the first lines that are visible are

File "/usr/local/www/freenasUI/tools/sync_disks.py, line 61, in <module> main()
File "/usr/local/www/freenasUI/tools/sync_disks.py", line 56, in main _notifier.sync_disks(dev)
File "/usr/local/www/freenasUI/tools/../../freenasUI/middleware/notifier.py", line 4218, in sync_disk
disk.disk_serial = self.serial_from_device(devname) or ''
File "/usr/local/www/freenasUI/tools/../../freenasUI/middleware/notifier.py", line 3958, in serial_from_device
output = p1.communicate()[0]
[...]
KeyboardInterrupt
Script /etc/rc.d/devd interrupted
Script /etc/rc.d/devd running
[...]​

I can try to get the rest of the trace if it is important.

Any ideas where to start looking to fix this? When I can reboot this machine next time I will try to turn SMART service off before updating to 9.2.1.9 to see if it would work better.

Does the system boot OK if you try booting it from a stick written with 9.2.1.9?

I will try upgrading when I can. Reboot with S.M.A.R.T. service turned off seemed to work... smartd did not work without modifying smartd.conf manually, anyways, for this I filed a bug report
