Yes.

John, can you tell anything about another case, for which interrupt 
counters are:

db> show intrcnt
irq1: atkbd0            1
irq4: sio0              3
irq6: fdc0              2
irq9: acpi0             345147
irq14: ata0             1
cpu0: timer             57995

Does this also show an interrupt storm? This one has happened without bge 
in kernel. I'm asking because I've seen several different scenarios of 
hangs and this is from one of them. I'll try to reproduce all cases and 
gather interrupt statistics from all of them. I'm wondering can't all this 
cases be caused by one common reason behind all of them.
