I completely upgraded to 1.3BETA.  Still can't boot the SBC kernel, gives
the same panic as above.

When I use a ncrsci kernel, I no longer get kernel panics with
disklabel or fsck (a big step in the right direction), but 
fsck complains about "cant read block"...  For a small (1-5)
number of blocks.  The numbers change each time I run fsck
even if I run fsck -f several times in a row.  Also, after
I mount the zip, I can copy small files and cksum them,
but a larger file won't cksum right after copying it. In
fact I get different cksums when I re copy the file.  Obviously
a bad feature for backups.

Is this one of the things which should go away if I am able to
boot a later SBC kernel?

Your how-to was quite useful.  Some of the numbers were different
and after I get the entire process to go without errors, I'll
send you any diffs I find.

Dan

ps, boot log attached
