I have a bunch of Sun Fire X2100 M2 which lack PS2 too, but USB keyboard is working fine.

Do you have model where IPMI card have shared NIC port with standard on-board NIC? Intel 5520 Tylersburg based Twin servers have IPMI + KVM integrated onboard with dedicated third NIC port. May I expect problems or am I save with dedicated port? There are 4 NIC ports on Sun Fire X2100 M2, where 2 are nVidia and 2 are Broadcom (bge). One of those bge is shared with IPMI + KVM, but in this case, it works fine for more than year with hw.bge.allow_asf="1" in loader.conf. No locks, no packet loss. What is model number of your servers? Thank you for your reply Miroslav Lachman
