freebsd stable - Feb 2005 - 5.3 on IBM/Intel Blade server?

[Re-posted from -hardware, perhaps someone here has some insight]

I have an Intel blade server (just OEM'd IBM Bladecenter) with SBXL52 
blades running FreeBSD 5.2.1. The story under 5.2.1 was that either the 
keyboard would be active or the network would be  active but not both 
at the same time (if I booted with ACPI disabled the keyboard worked 
but not network, booting with ACPI got the network back but no 
keyboard). To install I had to do a scripted sysinstall over PXE boot 
which worked.

Now I'd like to run FreeBSD 5.3, I got it to install as an upgrade of 
5.2.1, when I boot up with ACPI enabled I can access the keyboard and 
the network interfaces appear in ifconfig but will not respond to any 
traffic. If I boot with ACPI disabled I can use the keyboard but the 
network interfaces will not appear in an ifconfig.

Does anyone have any suggestions? It seems like something minor, like I 
said the interfaces come up I can ping them from the blade itself but 
not from outside it (nor can the blade ping out). These are the built 
in bge interfaces.


Thanks,

Just a follow up to my message from the other week, it looks like we 
are experiencing the same problem as described in this PR:

http://www.freebsd.org/cgi/query-pr.cgi?pr=68445


Only the suggested "fix" in the PR doesn't work for me. Does
anyone
have more information on this issue? The PR is still open.


Thanks,
Paul
