Hi Eric,

I just did the procedure you asked for and this are the results:

ATAPI device at targ 0, lun 0 lastlun 0x0
model _NEC DVD-RW ND-2500A
stat 50, err 0
cfg 0x8580, cap 0xb00
cyl 0, hd 0, sec/trk 0
mult1 0x0, mult2 0x0
advpiomode 0x3
minpio 120, minpioflow 120
dwdma 0x7
PCI-device: [EMAIL PROTECTED], ata 0

Doing F1-A at the moment my machine is freezing doesn't throw me to the kmdb 
debugger :-(  My machine freezes after selecting an installation option 
(example: 6 Single User Shell).  By adding a lot of prom_printf's I came to the 
conclusion that my machine freezes at the moment the Mode Sense Page 3 request 
command is sent to my DVD-WRITER (sd_get_physical_geometry). The actual freeze 
seems to be caused by SD_BEGIN_IOSTART in the sd_uscsi_strategy function (file 
http://cvs.opensolaris.org/source/xref/on/usr/src/uts/common/io/scsi/targets/sd.c)

[b]sd_uscsi_strategy[/b]
            |
sd_send_scsi_cmd
            |
sd_get_physical_geometry

Thanks a lot
Best regards,
Ivan
