Can't mount root

[Martin Husemann <martin%duskware.de@localhost>]

Hi folks,

thanks to all the helpfull people I now have working serial console working.
I have a few minor nits and a big problem, nits first:

and a custom kernel says:

cpu0 at mainbus0: KA49, NVAX, 10KB L1 cache, 256KB L2 cache
[..]
spx0 at vsbus0 csr 0x38000000 vec 514 ipl 15 maskbit 2
spx0: Using QVSS 8x15 font                            
spx0: RAMDAC ID: 0x4a, Bt459 (SPX/LCSPX) RAMDAC type

but no traces of th TC adapter (nor the fta in it).

On the other hand the ramdisk install kernel:

cpu at mainbus0 not configured

and no traces of the framebuffer (nor TC adapter either).

So, is the unconfigured cpu a problem? Why is spx0 not in the install
kernel? Why doesn't it find my TC adapter?

But the real problem: it hangs completely after trying to mount root:

boot device: ze0                                                            
root on md0a dumps on md0b
root file system type: ffs

and that's it. If I send a break it drops to the bootmonitor. Same happens
for the custom kernel with root on NFS (and DDB configured). I expected
break to drop to DDB somehow, and of course mounting / to work ;-)

Am I doing something wrong?
