panic at serial boot

Hi Ho,

I'm trying to install FreeBSD 10.0-CURRENT snapshot from 23.03.2013 on 
a Dell M620 blade.
However, I'm getting a panic and drop to db while booting.

Looks like that:

Root mount waiting for: usbus1 usbus0
ugen0.2: <vendor 0x8087> at usbus0
uhub2: <vendor 0x8087 product 0x0024, class 9/0, rev 2.00/0.00, addr 2>

Any idea where to go from here?

initially I tried 9.1-STABLE snapshot from the same date, but that one 
doesn't even give serial output while booting. odd thing, but that's 
another story.

I just thought since I'm giving -current on this hardware a short and 
there is a problem, it might be worth reporting.
Anything I should do?

Cheers,
Marian

PS.: What I really like to do here is get FreeBSD 9.1-RELEASE or 
-STABLE up and running on a blade like that. But it looks like this will 
fail anyway since the broadcom BCM57810 nic is not (yet) supported in 
FreeBSD. I contacted the authors of bxe(4). Friendly folks! :)
