I have a kernel/world from r274273 sources, which is exhibiting a new
issue on my old laptop.  Neither 'shutdown -p now' nor 'shutdown -r now'
work.  I get to the end of shutdown and see for example

All buffers synced
Uptime: 4h23m15s

and then the laptop just sits there.  It does not power off with
the -p option nor does it reboot with the -r.  Has anyone else
seen this behavior?

The problem appears to be related to a recent change in the
USB stack.  If I have the following drive plugged into a
usb port, the above behavior is observed on shutdown.


hw.usb.no_shutdown_wait: 1

to /boot/loader.conf appears to work around the 'shutdown -p now'
and 'shutdown -r now' issue.  Unfortunately, the bricking of the
laptop is not affected by this sysctl.  Once a device is plugged
into a usb, it must remain plugged in.


Is using this sysctl/tunable a suitable solution for you?
