interrupt storm detected

I have a recent install of FreeBSD 11.0-RELEASE-p1, and after installing a
Marvell 88SX7042 PCIe card from my old FreeBSD 10 system and I'm getting
the following message:

interrupt storm detected on "irq26:"; throttling interrupt source

This is a new system (old hardware), a Tyan S7012 dual LGA1366 board, 2
x5650 CPUs, full 18 banks of 4GB ECC RDIMM memory (checked with memtest86
before installing OS).

At first I saw it in the console after the system was fully booted,
scrolling pretty fast. I install smartmontools package and immediately saw
a a reset and the messages stopped. I then rebooted a few times and tried a
power off/on (not fully removing power though, just soft-off) and now I'm
seeing it during the boot process but not after booting all the way up. In
the /var/run/dmesg.boot I'm seeing several similar messages, seems to be
for each of the 4 channels:

(aprobe1:mvsch1:0:15:0): SOFT_RESET. ACB: 00 00 00 00 00 00 00 00 00 00 00
(aprobe1:mvsch1:0:15:0): CAM status: Command timeout
(aprobe1:mvsch1:0:15:0): Error 5, Retries exhausted

Along with the interrupt storm message above. I did check vmstat -i and see
that irq26 is indeed the mvs0 (Marvel) controller:

vmstat -i | grep irq26
irq26: mvs0                         1062          0
irq260: igb0:que 4                  2122          1
irq261: igb0:que 5                  4349          2
irq262: igb0:que 6                  2123          1
irq263: igb0:que 7                  2119          1
irq264: igb0:link                      2          0
irq265: igb1:que 0                  2100          1
irq266: igb1:que 1                  2100          1
irq267: igb1:que 2                  2100          1
irq268: igb1:que 3                  2100          1
irq269: igb1:que 4                  2100          1

I also don't see the 4 drives plugged into the controller, just the drives
plugged directly into the motherboard.

Do you think the card is bad? Or is the more sophisticated chipset/cpu
hardware/bios not as forgiving?
