Description phiber 2001-11-14 05:10:00 UTC 
Since doing a full "make world" upgrade from 4.3 to 4.4, neither shutdown
nor reboot act as expected.  My Sony VAIO 505EX shuts down cleanly, it
syncs the disk, prints the uptime, then locks SOLID.  Ctrl-Alt-Del won't
work, and I have to hard power-cycle the laptop.  This is affecting reboot
as well as shutdown -p and shutdown -h.  All freeze after the uptime is
displayed.  This didn't happen with 4.3, nor as far back as I can remember
(2.2.x and 3.x always shutdown/rebooted fine with PAO, FWIW).  Turning off
APM made no difference, so I doubt that's related...

How-To-Repeat: Try shutting down or rebooting, and it will hang solid after printing
the uptime, every single time without fail.

Just a little update...  I've discovered that this problem ONLY occurs if a
PCMCIA card is in the machine during reboot or shutdown.  If the slot is empty,
the laptop will reboot or shutdown as normal.  If the slot is full (e.g. with
my 3C589), the machine will hang on reboot or shutdown.
This is the only time I've experienced PCMCIA related hangs with 4.4-RELEASE.
My ethernet card works fine during normal system use.  Suffice to say this did
NOT happen with previous versions of FreeBSD.  Also of note is that I had to
add...

hw.pcic.intr_path="1"
hw.pcic.irq="0"

...to /boot/loader.conf after doing my initial install, since the machine would
panic otherwise.  But everything seemed fine after this, only the reboot and
shutdown weirdness remains.
In adding some printf's to /sys/kern/kern_shutdown.c, it would appear that
when the PCMCIA slot is occupied on shutdown, the machine hangs when
EVENTHANDLER_INVOKE(shutdown_post_sync, howto)
is called on line 310.

Does this still happen with more recent releases?
