Very unlikely, it would definitely show further progress (at least is
this the case if you experience such an issue on a real sparc box).
The unique Solaris(2.)6++ install media (CD/DVD) layout is a ways more
suspicious candidate here.
Especially that those media contain ufs slices among others (strange
enough that they got more than one slice at all).
BUT, unfortunately is is either NOT the reasons, OR it is one of at
least two reasons.
I got exactly the same behaviour when trying to boot Solaris(2.)8_hw2004
from the raw "/" slice of my physical hdd :(

I mean the opposite.
The world uses 2048 byte disk block size on the CD.
You mean 512 byte block size.

(though there is still a freeze when the scsi driver tries to load
during SPARC_LinUX guest boot / wasted a day, modified *latest* proll
sources and rebuilt proll several times, also diff. files in
[QEMU-root]/hw and [QEMU-root]/target-sparc, but didn't find a solution
that late-summer day in September)
