Hi! all,


My prep machine(Model 7248) not boot at 201202051330Z.
I think happen the hangup on usr/mdec/boot.  no message and a
under-bar'_' only displayed on screen.

And, old boot(last 3-month?) and kernel(201202051330Z) hangups
after this message.

root on sd0a dumps on sd0b
root file system type: ffs


This problems happen on me only?  X-<

Thanks,
