I have the same problem on my LCII with a quantum drive.  The only kernel
I have had success with is SBC #15.  The later SBC kernels freeze up at
the same place "sbc0 at obio0: options=1<PDMA>" except for #26 with
freezes at a different line.  I forget where it freezes, I haven't tried
booting it in a while.
