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
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
