I'm trying to put gentoo onto a multi-process Sun box. I'm using the
sparc64-universal-2004.3 liveCD. I can boot the kernel (gentoo-2.4-smp)
just fine. However, when it tries to mount the cdrom into /newroot, it
fails with a "Can't find root block device" message.

If I go into the shell, and I try 'mount /dev/sr0 /newroot' (or any
combination, including /dev/scsi/host1/bus0/target6/lun0/cd), mount
fails with an "Invalid Argument."

Any ideas as to what's going on?

Perhaps you need the 'doscsi' boot option.

No joy. Interestingly, that list of kernel options doesn't appear
in the Sparc handbook:
http://www.gentoo.org/doc/en/handboo...?part=1&chap=2

I did try doscsi, docache and noapic (and various combinations
thereof), but none of those seemed to help.

Weird.

Sorry it didn't help. Perhaps this would be more fitting:

No, that's not it, either. Doing a 'boot cdrom' works, since the
kernel is getting loaded. It's the linux kernel that can't mount the cdrom.

I can see while the kernel is getting loaded up that it correctly
dectects the cdrom drive, and there's a
/dev/scsi/host1/bus0/target6/lun0/cd block device that *should* be the
CDROM.

Hmm. That's interesting. I can't mount /dev/sda3 to /newroot,
either. Heck, I can't mount *anything*. I get "Invalid Argument" for
everything. That's really strange.
