Re: 6.0-BETA5 panic at shutdown with ULE scheduler

This is easily reproduceable. Backtrace and kernel config are attached.

This only happens when I'm using my ThinkPad as a gateway. If I do the
following... 

kldload ipfw
kldload ipdivert

sysctl net.inet.ip.forwarding=1
sysctl net.link.ether.ipfw=1
sysctl net.inet.ip.fw.verbose=1

ipfw add 100 divert 8668 ip from any to any via em0
ipfw add 101 allow ip from any to any via em0

... I will get this panic when I shut down. It may require that traffic
be coming or going through the network interfaces when I shut down.

The network devices on this laptop are:

ath0_at_pci2:2:0: class=0x020000 card=0x057e1014 chip=0x1014168c rev=0x01 hdr=0x00
    vendor   = 'Atheros Communications Inc.'
    device   = '11a/b/g Wireless LAN Mini PCI Adapter'
    class    = network
    subclass = ethernet

em0_at_pci2:1:0:  class=0x020000 card=0x055b1014 chip=0x10778086 rev=0x00 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82547EI Gigabit Ethernet Controller (Mobile)'
    class    = network
    subclass = ethernet

I'm happy to test patches. Please let me know what other information I
can provide.
