I have an em device that fails to attach after this commit:

em0 at pci0:0:25:0: class=0x020000 card=0x00018086 chip=0x294c8086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82566DC-2 Gigabit Network Connection'
    class      = network
    subclass   = ethernet

em0: <Intel(R) PRO/1000 Network Connection 7.4.2> port 0x3400-0x341f mem
0x92200000-0x9221ffff,0x92224000-0x92224fff irq 20 at device 25.0 on pci0
em0: Using an MSI interrupt

At this point the machine waits for about half a minute and then continues
with this:

em0: The EEPROM Checksum Is Not Valid
device_attach: em0 attach returned 5
