We have a system based on Supermicro X7SPA-HF with IPMI connected via a
shared 82574L NIC. We are not using this NIC for anything from the OS but
the probing and device attach breaks the IPMI connection so bad FBSD don't
see any screen during boot. There is no BIOS flag that disables the NIC
from the OS, only a HW strap but that dsables the IPMI also.
Is it possible to disable the probe of the NIC using hists to the PCI bus
driver? I have addded hint.em.0.disable=1 but it does not help.
em0@pci0:2:0:0: class=0x020000 card=0x10d315d9 chip=0x10d38086 rev=0x00
hdr=0x00
vendor = 'Intel Corporation'
device = '82574L Gigabit Network Connection'
class = network
subclass = ethernet
Any other suggestions appreciated.
