I also get interrupt storms with msk.  They do fix themselves when they 
happen, and I've seen it happen with the machine is idle.  This is on my 
little netbook where msk had several problems initially that have since been 
fixed.

mskc0: <Marvell Yukon 88E8072 Gigabit Ethernet> port 0x2000-0x20ff mem 
0xe0000000-0xe0003fff irq 19 at device 0.0 on pci32
msk0: <Marvell Technology Group Ltd. Yukon EX Id 0xb5 Rev 0x02> on mskc0
msk0: Ethernet address: 00:24:81:40:e3:ef
miibus0: <MII bus> on msk0
e1000phy0: <Marvell 88E1149 Gigabit PHY> PHY 0 on miibus0
e1000phy0:  none, 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
1000baseT-master, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow

mskc0 at pci0:32:0:0:      class=0x020000 card=0x3056103c chip=0x436c11ab 
rev=0x10 hdr=0x00
    vendor     = 'Marvell Technology Group Ltd.'
    device     = '88E8072 PCI-E Gigabit Ethernet Controller'
    class      = network
    subclass   = ethernet
