HARDWARE= DELL 1955 BLADE 
OS Version= CURRENT i386(2007-02-01) 

When I assign an IP to one of the BCE interfaces on the system the kernel
PANICS.

>From KDB:
---------------------------------------------------------------
Panic: invalid ife->ifm_date (0xa) in mii_phy_setmedia 

Cpuid = 0 
KDB: enter:panic 
[ thread pid 715 tid 100041]
Stopped at kdb_enter + 0x2b:nop
---------------------------------------------------------------

I then type "panic" and it writes a vmcore dump.  

But when I analyze the vmcore using kgdb and run a "bt" it only gives me the 
backtrace of the kdb and shutdown. 

Is there a way to write a dump without kdb interfering?

Another thing, I tried to install CURRENT-snapshot-2007-01(AMD64), but after it
boots from the USB DVDROM. Sysinstall cannot access the USB DVDROM. 
Is this a known problem?
