freebsd stable - Apr 2010 - sysctl(?) problem on boot in 8-STABLE

Hi,

I upgraded an 8-STABLE box to r206119 and am now unable to boot
multi-user.  I found that it hangs at line 58/59 of
/etc/rc.d/initrandom:

( ps -fauxww; sysctl -a; date; df -ib; dmesg; ps -fauxww ) \
                    | dd of=/dev/random bs=8k 2>/dev/null

when I run each of these commands by hand, I get only as far as
'sysctl -a', which seems to exit normally but leaves my keyboard
unresponsive (actually acting like I'm leaning on the <enter> key).
more digging reveals 'sysctl dev.uart' to be what triggers it.

this is the entirety of dev.uart from r204154:

dev.uart.0.%desc: 16550 or compatible
dev.uart.0.%driver: uart
dev.uart.0.%location: handle=\_SB_.PCI0.UAR1
dev.uart.0.%pnpinfo: _HID=PNP0501 _UID=1
dev.uart.0.%parent: acpi0
dev.uart.0.wake: 0

seems about the same from r206119.

I've attached boot output from r206119.

Any ideas?  any other info I need to provide?

thanks much,
Jeff

kern/143040 looks similar.
