Hi All,

I have sNV b78 installed (I know I'm working on upgrading to b90.)

I was attempting to mount /dev/dsk/c2t0d0s4, which is an ATAPI DVDROM 
drive containing S10 03/05 CD1, and the machine panic'd when I did 
'mount -F hsfs -o ro /dev/dsk/c2t0d0s4'

Here's what came up on the console... I can try to get the core also if 
needed.

panic[cpu0]/thread=ffffff02d5810140: BAD TRAP: type=e (#pf Page fault) 
rp=ffffff0010896a20 addr=20 occurred in module "mntfs" due to a NULL 
pointer dereference

If there's a better email list to post this to, please let me know.
Or if this is a known issue, is it fixed in b90?
