Enabling MD_ROOT_SIZE specifies that a MDROOT has been compiled into the kernel, and gives its size so the volume will be appropriately initialized. So specifying this option in the beginning was a mistake. There is absolutely no need for MD_ROOT_SIZE in any production kernel, unless you are booting diskless or some other special need. I think we have to blame PEBKAC on this although a word of caution in NOTES is probably warranted. > > > ________ > > > On Sun, 7 Dec 2003, Doug White wrote: > > > On Sat, 6 Dec 2003, Wesley Morgan wrote: > > > > > > Eh, this is you hitting the gdb key. how about 'ps'? > > > > > > Hooray for serial consoles! > > > > You didn't compile with BREAK_TO_DEBUGGER? you still hit the ddb key :) > > > > I'm still not seeing anything hanging.
