Yes...We see the same stuff on our ANS. The problem seems
to be that the internal scsi bus doesn't seem to get reset
properly or initialized properly, and the linux SCSI code
thinks that things are running along smoothly, and the reads
to get the superblock from your HD are returning garbage
data to the kernel. I haven't the foggiest how to fix
the kernel to get it to work right...but an interesting note:
Put a vmlinux on an external drive, set OF to boot off of
the internal drive's Quik, then tell quik to boot the
external drive's kernel, giving it a root command line arg
to tell it to use the internal drive as the root fs. It
all works magically now (well, ours does). Very odd.
