ahci0 at pci0 dev 31 function 2 "Intel 82801GBM AHCI" rev 0x02: apic 2 int 16 (irq 11), AHCI 1.1 em0 at pci1 dev 0 function 0 "Intel PRO/1000MT (82573L)" rev 0x00: apic 2 int 16 (irq 11), address 00:16:d3:c0:22:c8 em0 is not really generating interrupts on the line the OS has detected but some other line (i.e. the OS didn't correctly determine how interrupt routing is done on your machine). by forcing the disk controller to generate interrupts it is causing the NIC's service routine to be run. I'd try a bios update, looks like there are some newer ones for your machine.
