em (e1000) card lockup on 8.1-RELEASE, plus rebooting

Hello.
We're experiencing strange issues in a server with 6 em ports (2 pci-express dual-port cards and 2 ports on the motherboard).
em0 / em1 are on a dual-port gigabit card, and in a few days we've experienced this issue first with em1, then with em0 (across different reboots):
The em card stops generating interrupts, and thus it stops receiving packets. After that, it only registers "input errors".
All other 5 em ports seem OK.
Trying to reinit the card with something like:
server# ifconfig em1 down;ifconfig em1 up; ls
...results in the server rebooting.
Now, our setup is a bit complicated. em interfaces aren't used for IP directly, but they have a few VLANS each.
We have in /boot/loader.conf:
autoboot_delay="3"
hw.em.rxd=4096
hw.em.txd=4096
net.isr.maxthreads=8
I've loaded pf and netgraph, more precisely ng_ether and ng_netflow.
The netgraph config looks something like (with vlan numbers and IPs changed):
/usr/sbin/ngctl -f- <<-SEQ
mkpeer vlan111: netflow lower iface0
name vlan111:lower netflow
connect vlan111: netflow: upper out0
connect vlan222: netflow: lower iface1
connect vlan222: netflow: upper out1
connect vlan333: netflow: lower iface2
connect vlan333: netflow: upper out2
connect vlan444: netflow: lower iface3
connect vlan444: netflow: upper out3
msg netflow: setconfig { iface = 0 conf = 3 }
msg netflow: setconfig { iface = 1 conf = 3 }
msg netflow: setconfig { iface = 2 conf = 3 }
msg netflow: setconfig { iface = 3 conf = 3 }
msg netflow: settimeouts { inactive = 15 active = 150 }
mkpeer netflow: ksocket export inet/dgram/udp
msg netflow:export connect inet/1.1.1.1:1234
SEQ
pf uses a few rules on two vlans, and has "set skip on em" "set skip on vlan111" etc (only enabled on two vlans, and we don't use netflow on those).
The machine is an external router, so it has a full BGP routing table (330k routes).
Other tuning: rx,tx (normal and abs) int delays are all 0, for all cards.
/etc/sysctl.conf:
net.inet.ip.fastforwarding=1
# I know the next one is useless with flowtable.enable=0
net.inet.flowtable.nmbflows=1000000
net.inet.flowtable.enable=0
net.inet.ip.intr_queue_maxlen=4096
net.route.netisr_maxqlen=1024
net.inet.ip.redirect=0
net.inet.ip.process_options=0
Some info from when the system was running, but with em1 hung:
sysctl net.em.1.stats=1:
em1: Excessive collisions = 0
em1: Sequence errors = 0
em1: Defer count = 0
em1: Missed Packets = 714538
em1: Receive No Buffers = 20793
em1: Receive Length Errors = 0
em1: Receive errors = 0
em1: Crc errors = 0
em1: Alignment errors = 0
em1: Collision/Carrier extension errors = 0
em1: watchdog timeouts = 0
em1: XON Rcvd = 0
em1: XON Xmtd = 0
em1: XOFF Rcvd = 0
em1: XOFF Xmtd = 0
em1: Good Packets Rcvd = 2806530411
em1: Good Packets Xmtd = 2681378150
em1: TSO Contexts Xmtd = 0
em1: TSO Contexts Failed = 0
sysctl net.em.1.debug=1:
em1: Adapter hardware address = 0xffffff80005e4590
em1: CTRL = 0x400c0241 RCTL = 0x4008002
em1: Packet buffer = Tx=16k Rx=32k
em1: Flow control watermarks high = 30720 low = 29220
em1: tx_int_delay = 0, tx_abs_int_delay = 0
em1: rx_int_delay = 0, rx_abs_int_delay = 0
em1: Queue(0) tdh = 1805, tdt = 1805
em1: TX(0) no descriptors avail event = 0
em1: TX(0) MSIX IRQ Handled = 0
em1: Num Tx descriptors avail = 4096
em1: Tx Descriptors not avail1 = 0
em1: RX(0) MSIX IRQ Handled = 0
em1: hw rdh = 309, hw rdt = 309
em1: Std mbuf failed = 0
em1: Std mbuf cluster failed = 0
em1: Driver dropped packets = 0
Attached you will find dmesg.boot and pciconf -lvc.
The kernel config is the 8.1-RELEASE(amd64) GENERIC with three added lines:
device crypto
options IPSEC
options TCP_SIGNATURE
These are for a TCP MD5 authenticated BGP session which doesn't go through either of the two affected interfaces.
The kernel gave no messages when em1 stopped working. All other em cards (em0, em2, em3, em4, em5) seemed to be working fine.
So, to recap: em1 stopped receiving packets (two nights ago, it was em0 with the exact same issue); doing "ifconfig em1 down;ifconfig em1 up" reboots the machine (didn't have console access at the time; don't know what exactly happened).
The error happened at aroung 40kpps in, 40kpps out (counting only em1); two nights ago it was em0 who locked, and it was doing ~20kpps in each direction. After the em1 lockup em3 (working) went from 30 to 70kpps out (and 20->35 kpps in), no issues.
As a side note, when having flowtable.enable=1, a large routing table change (at least 50000 changed routes) makes flowcleaner take 100% of one CPU. It stays there for hours even if I do flowtable.enable=0 in the meantime; the machine seems responsive though.
Many thanks
Alex
