Mine are shared interrupts as well, however, they are shared among
the nics, so disabling is not an option
% vmstat -i
interrupt total rate
irq1: atkbd0 5 0
irq4: sio0 61332 0

em1 is the one having the problems (and yes, I did check the eeprom issue)
em1@pci1:0:1: class=0x020000 card=0x115e8086 chip=0x105e8086
rev=0x06 hdr=0x00
vendor = 'Intel Corporation'
device = 'PRO/1000 PT'
class = network
subclass = ethernet
cap 01[c8] = powerspec 2 supports D0 D3 current D0
cap 05[d0] = MSI supports 1 message, 64 bit
cap 10[e0] = PCI-Express 1 endpoint
its also in FastE mode and not gigE. Not sure if that makes a
difference or not.
