Pavilion g6 2147sl. The installation disk's loader runs, the kernel starts to 
boot then hangs. No strange messages come out (even with verbose output turned 
on) and the boot process stops there. Everything seems to be recognised in a 
proper way (usb3, ahci, re0 network card, etc).

even go to ddb. But if I remove the cd from the tray, the status change gets 
detected and the kernel prints something on the screen.

Does 9.1 fail to recognize the on-board disk?  I've seen several reports of 
9.1 failing to discover certain SSD's but working ok with spinning disks on 
IBM laptops where 9.0 worked fine.
