gbde atttach on sparc64 = kernel panic

Sun May 4 20:48:31 PDT 2003

I've been playing with gbde on the latest sparc64 current (last saturday
anyhow), everytime I try and "gbde attach *devicename*" I get a kernel
panic - I'm trying to attach gbde to the md() device (which in turn is
pointed at a file on a ufs1 filesystem).  More details below:

/usr/src/sys/sparc64/conf/GENERIC - unchanged, except for options GEOM_BDE
was added.
