Interrupts may not be functioning.
To be clear, you only see this at the end of reboot, and the hardware is fine once the machine is back up? > This problem was also obeserved with real 1068 hardware: > http://lists.freebsd.org/pipermail/freebsd-stable/2011-September/063937.html > > When I power off the virtual machine instead of rebooting, the problem > doesn't occur. > > Accidentally I found a workarround ;-) : > If I set 'verbose_boot' in loader.conf, the problem vanisehs!?!?!? > > Any idea how „verbose_boot“ affects the operation of the mpt driver? Extra printfs affect the timing most likely. Are you using any RAID volumes? The only shutdown handler in mpt that looks like it might want interrupts to work is mpt_raid_shutdown(). It needs to use polled I/O instead of disabling interrupts I think.
